Siheyuan: I eat melons while doing scientific research

Chapter 1354 How did this window get broken back? (6k)

Ground-to-air and ship-to-air radars—not to mention that a single radar system contains more than one unit, their size is also far superior to that of fighter jets; a single radar is heavier than the combined radars of an entire squadron of fighter jets.

So it's acceptable that they can fight against several opponents at once, even if the technology isn't advanced enough. To put it bluntly, they could achieve the same effect by using several vehicles for guidance.

However, fighter jet radar is different. It's only so big, and there's no extra antenna or radio frequency system to achieve this goal. In other words, it relies entirely on a single antenna backend to do the work, and this system is only so big.

On this basis, the fact that they were able to actually win 6 against 2 was far beyond what the comrades expected.

"This thing is so small, how can it compete with 6 against 2?" One comrade couldn't help but ask. Overall, there was not much controversy at the acceptance meeting. The only problem was that the results were a bit too unexpected.

The chief engineer of the radar institute nodded and smiled, "Yes, this is because the PD-63 is limited by the nose diameter of the fighter jet, so it can only do this much. Parameters such as detection range are also limited."

The nose diameter of the Z-7 fighter jet is based on that of the MiG-19. No matter how much it is expanded or retained, it is always limited by the diameter of the fuselage.

So this statement is a truth, but sometimes, the truth is the most hurtful.

So you guys think this parameter isn't good enough?

This basically means that under the current combat environment and conditions, half of the aircraft can confidently rush up to engage the enemy. Especially with its 100-kilometer detection range, twice the number of enemies is not very useful. On the contrary, having more targets provides a wider range of choices.

"This...do you have any achievements?" After thinking for a long time, one comrade finally came up with this question.

"Yes, yes, we have them all. We once used this skill to drive away enemy aircraft from 60 kilometers away," the comrade from the radar institute laughed.

Speaking of this, the Air Force comrades couldn't resist joining in. Their recent masterpiece was something that couldn't be discussed in general, but today, everyone in this unit was qualified to know about it: "Yes, this matter does exist, and we can reveal that the enemy is the Wang Guolao."

They were referring to the incident at the South China Sea's South Reef Islands, where our fighter jets, with their radars activated, forced the Kingdom's aircraft, which had launched from Lushon, to turn back. This feat is documented.

The assurances from the Air Force personnel made the authenticity of this matter extremely clear.

Moreover, this is the air force of the Kingdom of God, not some small fry. If it were planes from Heaven, the persuasiveness wouldn't be as strong, after all, taking down a defeated dog with its tail between its legs is no match for the Kingdom of God.

For a moment, the comrades felt it was all a bit unreal. They believed that our airborne radar had made great progress, and they were very confident in it.

Even the most confident comrades dared not imagine that progress could be made to such an extent. Judging from the radar institute's reports, combat examples, and the current state of airborne radar development worldwide, it is no exaggeration to say that this airborne radar is the best in the world.

It's not just about performance, but also about functionality.

The comrades at the radar institute were not satisfied with this: "The main function of this radar is air combat, but we believe that we can continue to develop its air combat capabilities and performance, and at the same time, we can also develop ground attack capabilities on its basis, turning our Zhan-7 into a true multi-role fighter jet, and taking our Gong-5's ground reconnaissance capabilities to another level!"

The comrades burst into applause; they had nothing to criticize and were too embarrassed to find fault.

For a radar that is clearly world-leading, any problems are not a problem. If you find any issues, you can just go down and have a few words of communication and that will be the end of it.

The comrades' beaming smiles made Gao Zhendong feel very comfortable watching from the sidelines. Also watching were the leaders and chief engineer of the National Defense Commission. Apart from the comrades from the radar institute who were actually doing the work, they were the two who knew best about Gao Zhendong's role in this.

The defense commission leader patted Gao Zhendong on the shoulder: "Zhendong, well done!"

Gao Zhendong shook his head: "I'm just talking; it's the comrades at the radar institute who do the running around."

The leader chuckled twice but didn't say anything more. Comrade Zhendong is just being modest!
Amidst the laughter and applause of his comrades, this radar, which had undergone long-term testing from last year to this year, was finally finalized!

The PD-63, the world's first advanced radar to integrate all the previous new technologies and achieve moving target detection, has finally been officially registered.

The final acceptance meeting was not long, lasting only about half a day. The main reason was that the results were advanced and highly completed, and even supported by various combat examples.

In this way, there was basically no dispute, and all aspects were handled very quickly and harmoniously, which is extremely rare in the acceptance of such important equipment.

Gao Zhendong had heard his mentor tell many amusing stories about his experiences during evaluations in his previous life; at times, they almost came to blows.

Just as everyone was walking towards the National Defense Commission's canteen, the chief engineer of the radar institute came up and walked out with Gao Zhendong.

Gao Zhendong barely spoke during the meeting today, mainly because he was extremely familiar with this topic.

Most of the new technologies mentioned here came from his hands. In a sense, Gao Zhendong is nominally an acceptance expert, but in reality, he is also one of the people being accepted today.

"Chief Engineer Gao, how about it? We didn't let you down, did we? Haha," the chief engineer of the radar institute laughed.

Gao Zhendong nodded: "Yes, that goes without saying. I can say that in this respect, you guys are much better than I am at using it myself!"

This isn't modesty or mutual flattery; it's the truth. Gao Zhendong dares to say he's better than his colleagues at every single new technology involved, but when it comes to actually combining them into a cohesive whole, the radar specialists are far more knowledgeable.

"No, no, no, I don't dare to respond to what you're saying, hahaha." The chief engineer of the radar institute laughed: "By the way, we've already started working on that atmospheric waveguide radar project that you guided last time, and the comrades are quite confident."

That's basically how scientific research works: the more success you have, the more confident you become, which is a positive feedback loop. And the colleagues at the Radar Institute are on this very path.

Gao Zhendong nodded as he walked: "Well, that's good. I haven't studied the details in depth either. We'll need our comrades to come up with more solutions for the details."

The chief engineer of the radar institute said, "You have already laid the foundation for this project using technologies such as traveling wave tubes and digital signal processors, and you have also found the theoretical path. We will take care of the rest. Otherwise, we would be embarrassed to call ourselves the radar institute."

The two men laughed, and after a brief pause, the chief engineer of the radar institute said, "Chief Engineer Gao, I remember the National Defense Commission once informed us about something. You said that radar can be used to create images, right?"

Gao Zhendong brought this up during a discussion about anti-submarine warfare.

Gao Zhendong suddenly realized that they were preparing the ingredients for the next batch of steamed buns as soon as the previous batch came out of the steamer.

Yes, that's true.

"The technology you're referring to must be synthetic aperture radar, right?" the chief engineer asked.

Synthetic Aperture Radar (SAR) matured relatively late, but like many other technologies, its theoretical basis was proposed much earlier. It was already being developed by scientists from the Kingdom during the North-South War. In this respect, one has to admire the Kingdom's talent; besides the locals, the outsiders were quite capable. After all, it was considered a peaceful land in S2. Aside from a few insignificant bombs dropped by the Beihai people's balloons, the mainland remained unscathed. Naturally, this attracted the people of the Southern Federation, who had suffered greatly from war, including a diverse group of highly skilled individuals.

Therefore, it is not that China is unaware of Synthetic Aperture Radar (SAR).

Gao Zhendong was not surprised by this and nodded: "Yes, that's it, and the prospects are very broad." If ordinary people have difficulty grasping the prospects of a new technology, then Gao Zhendong has no such problem at all. Among the future technologies proposed in this era, apart from the abnormal one like controlled nuclear fusion, he is very clear about the prospects of most technologies.

"That's great! You've already started research in this area? We have colleagues who are also working on this, but to be honest, it's still quite difficult right now." As a new technology that was only proposed 51 years ago, it's normal that we're facing some difficulties in developing it now.

What makes the colleagues at the radar institute happy is that Chief Engineer Gao is also reaching out into this field! Judging from his style and achievements, this most likely means that China may be able to make a big leap forward in the field of SAR!
What gives him such confidence is twofold: firstly, the basic technology is already sufficient to support the development of SAR; and secondly, in terms of theory, he believes that Gao Zhendong will never leave empty-handed once he reaches out!

This is not superstition, but trust.

Gao Zhendong was completely stumped. Since the last time he brought up this matter, there had been no follow-up, and he wasn't prepared at all.

Fortunately, he had some backup resources on hand, so he wasn't worried at all. He could prepare these things if he wanted to.

"Yes, it's just the beginning. Let's exchange ideas when you have time." Gao Zhendong wasn't intimidated. As for the physical objects, he might not be able to handle this in a short time, but as for the theory, he had no problem with it. After all, this was something that would be taught openly in university classrooms decades later.

However, having not yet begun, he naturally wouldn't delve into the details; he was completely in the dark and couldn't offer any explanation. But his words were incredibly gratifying to the chief engineer of the radar institute—it was a sure thing! A sure thing!
The radar institute didn't intend to slack off and rely solely on Gao Zhendong to do the work. However, with the help of someone like Chief Engineer Gao, the success rate and speed of this equipment will undoubtedly see a visible improvement.

Before Gao Zhendong's suggestion, the comrades were probably in a similar state of mind regarding PD radar, wanting to do something but lacking the ability to. But now, they have even launched a world-leading large satellite.

Chief Engineer Gao has already made significant achievements in radar. Although he doesn't delve into the details, he is undoubtedly a leading figure. With his efforts in SAR, I believe it will greatly help the progress of the work.

"That's great! We'll just have to swallow our pride and wait for good news," said the chief engineer of the radar institute. He knew very well that he couldn't set the timeline for this matter; who knew when Chief Engineer Gao would produce any preliminary results? So they could only wait for Gao Zhendong to summon them.

In this regard, it's not that radar was being lazy; rather, it was a case of having the will but lacking the capability. In the history before Gao Zhendong's time travel, we didn't truly enter the field of SAR until ten years later. This demonstrates the immense difficulty of this technology.

This is difficult, firstly because of the theory, and then because of the hard conditions. Now, thanks to Gao Zhendong, many of the hard conditions have been solved, but the theoretical problems still exist, and there has not been much improvement compared to Gao Zhendong's previous life.

“Okay, no problem!” Gao Zhendong didn’t hesitate, mainly because the radar’s uses were truly vast! There were so many places where it could be used.

Using radar to achieve 3D imaging does not require the line-of-sight conditions of visible light or lasers, and even if the resolution is lower, its usefulness is still immense.

Seeing the two discussing so enthusiastically, the defense commission leader and the chief engineer exchanged a glance, thinking, "That's the right way to do it."
-
In the north, in the country of Luo, a group of high-ranking bears, Big Bear and Little Bear, are struggling to make a decision because of our reply.

The reason they found it difficult to make a decision was not because the conditions were bad, but rather because the conditions were too good and too easy to accept. However, their demands were also high, which put them in a dilemma.

The person in charge of reporting this matter was Linochka, whose superior sat aside, listening to his capable subordinate speak eloquently.

"Comrades, this is the Southerners' response: straightforward, but greedy," Linochka concluded after explaining the situation.

To be honest, the joke about Luo Guo accusing others of greed is a bit hellish, roughly equivalent to the Kingdom talking about human rights every day.

"The Southern comrades' generosity on the semiconductor production line is somewhat beyond my expectations..." Linochka's superior, the leader in charge of our military exchanges, added.

According to his and Linochka's thinking, the Southern comrades would most likely not agree to sell the semiconductor production line. In this case, the request for aerospace-grade components would seem reasonable. The Southern comrades were quite mindful of the emotions of both sides, so the probability of this small request being met would increase under these circumstances.

The leader thought that Linochka's little trick should be effective.

But to everyone's surprise, the comrades from the South didn't hesitate at all and replied as quickly as possible – no problem, but you also have to show the same sincerity as us.

The speed of this action surprised even the leaders who were well aware of the time-consuming procedures involved in related matters.

But now a new problem has arisen, and pressure has been placed on them.

Comrade Nanfang's extremely straightforward attitude made Linochka's little tricks seem somewhat superfluous and ridiculous, and raised a new question—since we've been so straightforward, shouldn't you reciprocate?
This may sound a bit mercenary, but sometimes it can indeed influence a decision about a job.

The country that made the first move was pushed back against the wall because of our decisive attitude.

“Impossible, a marine reactor? That’s absolutely impossible!” a Luo Guo said decisively.

Decades later, the Great Bear, the successor to Romania, will indeed be leasing nuclear submarines, but Romania at that time is not in such dire straits. Of course, there might be a hidden motive in the Great Bear's decision to lease nuclear submarines to the Kingdom of Heaven, a move intended to sow discord among us.

“However, we have also exported nuclear technology to them before. Compared to nuclear technology, which can directly cause death, marine reactors are not actually that serious,” another person expressed a different opinion.

After all, they even gave it to Little Ivan back then. Although they withdrew it halfway through, that doesn't change the fact that it was given in the first place.

"Back then it was because... because... anyway, the circumstances are different now! The two cannot be equated!"

Most attendees agreed with his opinion, as acquiring the marine reactor would dramatically increase the threat posed by the enemy in the distant underwater region. Even though the distant region was not the strategic core of the Republic of Russia compared to the Southern Federation, and their naval power there was not particularly strong, its importance could not be underestimated. Conventional forces were one thing, but nuclear forces were somewhat beyond what was tolerable.

"If that's the case, then the space cooperation proposed by the other party..." The leader said, but suddenly felt that this matter seemed somewhat familiar.

He glanced at Linochka beside him and suddenly realized what was happening.

Suka Bulie!

Isn't this just a rehash of Linochka's broken windows theory? Only this time, it's being used against us instead.

For a moment, the leaders didn't know what expression to make. The comrades from the South were indeed not simple.

"We don't need any help!" It was the same person who opposed exporting shipboard nuclear reactors. It seems that his opposition to exporting shipboard reactors was not only due to various reasons related to the reactors themselves, but also to other factors.

This time, someone disagreed—it was someone from a certain aerospace design institute, responsible for the control system. Their reason for being there wasn't hard to guess; the cooperation request put forward by the southerners involved them deeply. Not only the control system, but also the person in charge of the overall project was present.

“Comrade, regardless of whether I agree with their willingness to cooperate, I must correct your view. We need help, especially help from our comrades in the South!” The person in charge of the control system did not hesitate. From a technical point of view, that was the case.

"Why? Since they've agreed to sell the semiconductor production line without making space cooperation a condition of the sale, we won't need their help after we acquire it. Don't you have confidence in your own technology?"

Graphite stacks are a prerequisite for the sale of semiconductor production lines, but space cooperation is not. After all, compared to graphite stacks, which can both produce PU and generate electricity, their importance at this stage is simply not as great.

However, this person's claim is a bit too grand. If their loving father were still alive, they might have inadvertently won a Gulag Hotel experience voucher by answering this question.

The person in charge of the overall project raised his hand, stopping the head of the control system from speaking. In this respect, the head of the control system was somewhat inexperienced. For the safety of his subordinates, he decided to answer the question himself.

"It's not that we lack confidence in ourselves, but I think we need a force to share the burden. For too long, we have actually been fighting the entire Antri Pact organization on our own. This is especially true in high-tech fields. Our motherland is too tired; she needs rest and to lighten the load on her shoulders."

His words silenced everyone. It wasn't that they didn't know about it, but rather that they were deliberately avoiding the topic.

The chief system engineer continued, “My comrades, we must know that the Kingdom is already seriously and relentlessly preparing to do something to the moon. Our comrades in Lubyanka have told us that their latest rocket has almost twice the carrying capacity of our largest planned rocket…”

This difference is roughly between 50 tons and 100 tons.

Everyone else present was taken aback; the gap was indeed quite large. Moreover, they all knew that since their side had won the first place in satellite and manned spaceflight, the only remaining space program with the highest political benefits and the relatively lowest technical difficulty was the lunar landing.

However, the difficulty is relatively low; it is relative to the fact that it involves landing on nine planets.

The actual difficulty is so great that even the Southern comrades, who are now recognized as the third in the world in aerospace technology and have their own unique advantages, dare not put forward any plans in this regard.

The people from the space design institute didn't stop talking: "We've done preliminary calculations, and in order to catch up with the Kingdom, we need to increase the number of engines in our planned large rocket from 24 to 30 in the first stage to increase the payload capacity from 50 tons to 95 tons..."

Another person laughed and said, "So what? Are we incapable of building a rocket that can fit 30 engines?"

He didn't understand the field of rocketry, so his thinking was somewhat simplistic.

"Comrade, the problem isn't whether we can fit them in, but whether we can control them! Controlling 24 engines is already very difficult, but controlling 30 engines would be disastrous for our technology and capabilities!"

It's true that Luo Guo is good at system integration, and it's also true that he's good at making something usable out of a bunch of junk, but the N-1 rocket far exceeds their current integration capabilities.

"Do people from the South really have this ability?" Some people expressed doubts about this.

The people from the design institute turned to look at him: "Comrades, I'm not sure if they have the capability, but I am certain that their capabilities in this area exceed our imagination. They have their own areas of expertise, and they are even stronger than us! Gentlemen of the Comrades, don't forget whose satellites we rely on to ensure real-time surveillance of the kingdom in a strategically significant way?"
