Chapter 268 Chris' Visit; Electromagnetic Wave Detector

In Zhou Changfeng's impression, this familiar figure was one of the two captain liaison officers sent by the Red Eagle Legion during the Battle of Talavera. Because we talked a few words at that time, and finally issued an order to expel the guests, I remember it very well. clear.

But because of the urgency of the situation, he didn't even have time to mention his name, so he didn't know the name of the blond, blue-eyed German.

There was a light of surprise in Chrissy's eyes. The Eurasian continent is so big, and the Ming Dynasty has such a large population. It must be a lie to see the commander of the [-]th Brigade again.

"It's from [shí]. In [zǎi] Talavera, I conveyed to you the order [míng] of the [sǐ] Command." Her plastic Chinese can be said to be full of German, with a proper Germanic accent .

"..." At this time, Zhou Changfeng didn't know what to say, and he held back for a few seconds before replying, "Why did you come to China all of a sudden?"

"I need it for work. I am now the military attache of the embassy."

At this time, Shen Yu, who was dressed in sea-blue civilian uniform, walked out from the side. He folded his arms and said with a smile, "Zhou Kexing, how did you two meet?"

Although there is some metaphysics, sometimes you can really feel the existence of "Qi". For example, although Zhou Changfeng didn't look at his side at all, he felt the dissatisfaction from Xia Xiaoshi.

A little embarrassed, he coughed dryly: "It's a long story, come in first."

Shen Yu was the first to cup his hands, and then Zhou and Xia also cupped their hands or bowed their bodies. Chris put her legs together, stood up straight and raised her hands in salute.

Seeing this, Zhou Changfeng hesitated for a moment, and raised his hand to salute her in return.

In Xia Xiaoshi's eyes, someone Zhou even said "wronged" before, but now it seems that she must be fooling herself!

Ah!Sure enough, what the man said was unbelievable!

Look at this Western woman again, she is so tall, with such fair skin, blond hair, and blue eyes, it is really strange.

So Xia Xiaoshi quickly had a brainstorm in her head, and analyzed what kind of intersection Zhou might have had with her, and whether she was a threat to herself, and how big the threat was...

The front yard is so small, just a few steps, the four of them went straight through the front yard and entered the main house.

Chris has lingering fears about the threshold set under the door to separate the inside and outside of the house—she tripped twice in the first two days when she first arrived, and she really couldn’t understand why Chinese people are used to setting such high things.

Sit down and serve tea.

Zhou Changfeng personally filled her with tea, and then glanced at Xia Xiaoshi and Shen Yu. The former looked a little uncomfortable and absent-minded, while the latter was contented.

Only then did he look at Chris, who was wearing a wild gray uniform with a top and a skirt, and asked, "The situation was not good at the time, everyone was very nervous and anxious, and it was not intentional to drive you away."

"That may be right, otherwise some units could not be delivered on time." Chris briefly talked about what she saw and did in Real after that.

The opponent refuses to cooperate with the heavy anti-aircraft guns?Then he killed a major of the Republican logistics unit on the spot?So this indirectly made the battle end more smoothly?

Hearing this, Zhou Changfeng was a little bit surprised when he was surprised—kill as soon as he said it, this courage is indeed extraordinary.

Because of the lack of study time, Chris's Chinese level is limited, but it is impossible to communicate in a foreign language on this occasion, otherwise who knows what code words or foreign language vocabulary she and Zhou used to communicate.

Although there were not many intersections at that time, the two still had a good talk, and in a sense they could be regarded as "comrades in arms".

On the side, Shen Yu seemed to be wandering aimlessly, but was actually listening carefully to the conversation between the two.

Just listening is not enough, you have to write it down, and when you go back, you have to write a report on the content of the conversation from memory.

As a guy with a criminal record, Zhou is already the care object of the foreign factory.Now he actually has contacts with the military attache sent by the Germans?Then it has to be upgraded to key care.

Gradually, their small talk turned to more professional topics.

"...How long did your landing operation on Tokyo Bay last?" Chris asked.

"This... within a day." Zhou Changfeng said casually.

"How many armored vehicles did you invest in? How long did it take to deploy? Are they effective?"

"A total of more than 30 tracked vehicles and more than 100 wheeled armored vehicles were invested in the troops landing in Tokyo Bay. The deployment time will definitely vary depending on the situation on the spot. The effect is... not bad."

Zhou Changfeng's ambiguous answer did not make Chrissy unhappy. This kind of inquiry can only be regarded as routine, and she herself did not intend to use it to extract any useful information.

Continue to get to the bottom of it?That would only bore the other party and quickly drain the shallow friendship between the two of them.

Obviously extremely unwise, there is no need to dig information from this guy for the time being.

When she learned that Zhou was going to return to the troops stationed in Tokyo in the evening, Chris said, "Thank you Lieutenant Colonel for your hospitality, I should go back to the embassy, ​​and I hope to see you next time. "

"Well, walk slowly."

The car started slowly, and disappeared at the intersection with one turn.

After sending her away, Zhou Changfeng and Shen Yu lit a cigarette each, and started talking while walking around the door.

"When I was in Spain, I thought she was just an ordinary military officer, but now it seems that she is just a disguised identity."

"Indeed, the military attaches sent by the Germans usually fall into two categories. One is an officer of the General Staff Department, and the other is an agent of the Security Bureau. I thought this person was the latter."

Zhou Changfeng nodded, and said: "What I'm afraid of is doing mental calculations without intention. Now that she has guessed her identity, she will definitely not pester her anymore."

Shen Yu was noncommittal, and changed the subject, "The Germans are still negotiating with the imperial court for the past two days, and they have brought a lot of things, big and small, and they seem to be sincere."

"Uh..." Zhou Changfeng pondered with a calm expression: "I'm afraid the Germans themselves have no idea what the specific strategic plan is, but for the sake of national defense and security, they really want an ally who can respond to each other from a distance. .”

"The imperial court will not consider it at all."

"Yes, the implications and costs of an alliance are too great to be worth it at this time."

Shen Yu said "hmm", "A long-distance friendship is a short-distance attack, a good friendship is a good friendship, a vow of alliance... Tsk, it is impossible, it would be good if we can maintain the current friendly relationship."

"Okay, I have to pack my luggage, and I should leave in half an hour." Zhou Changfeng pressed the cigarette butt that was about to burn out to the little stone lion in front of the house.

Just in the past two days, a research and development organization under the name of the Ordnance Bureau submitted an application to the Ministry of War-it is recommended to ask the German agency for information about the "electromagnetic wave detector".

This is a small-scale committee that has just been established for three years. The cause was that military officers and technical officials successively suggested to the army or the Ministry of War to develop "long-range aircraft detection machines."

After being adopted, several Air Force and Navy officers, technical officials, and engineers were appointed to lead the R&D project. This committee is called the "Electromagnetic Wave Detector R&D Organization Committee", or "Electrodetection R&D Committee" for short.

According to the phenomenon that "the radio waves emitted from the transmitter will be interfered by the radio waves reflected by the aircraft", the Air Force Gezhi Equipment Factory and Shanghai Yongchang Electric Company developed the first dedicated electromagnetic wave early warning equipment.In October of the 36th year of Zhichang, the prototype was tested in Huzhou Prefecture for the first time, and it was successfully found that there were aircrafts appearing in the general direction.

Its power is only a few hundred watts, and its operating frequency is 50MHz-60MHz, which belongs to ultrashort wave.

As the pioneering work of the Ming Dynasty's electromagnetic wave early warning equipment, this type of machine can only tell the general direction of the aircraft's appearance, other than that, the altitude, speed, heading, size and other data are completely unknown.

Dozens of this type of machine were produced in small batches, and they were deployed in the three border regions of the northwest, southwest, and southeast, as well as Gyeonggi.

Without demand, there is no driving force. During the Spanish Civil War, the role and power of the air force basically verified the rationality of the theory of "Air Command" written by Douhet.

While paying more and more attention to the air force and strengthening its own "spear", it is natural to strengthen the "shield" accordingly.

In addition to the research and development of a new generation of medium and large-caliber anti-aircraft guns being put on the agenda, the research and development of electromagnetic wave early warning equipment has also been greatly strengthened, and the resources available for research and development organizations, such as people, money, and materials, have increased significantly.

Just two months ago, the prototype experiment using the pulse wave system was successful, with an operating frequency of 100MHz and a maximum output power of 3.6kW. According to the actual measurement results of the Air Force, this type of machine can detect aircraft in flight at a distance of 18㎞, but Not very accurate.

The performance of the electromagnetic wave detector can only be described as "touching". For naval warships, this is not as far as the observation distance of the human eye when the weather is clear, but it can be said to be a good start.

However, is the level of this "beginning" high or low?Everyone wants to know.

Last year, at the International Radio Academic Conference held in Vienna, some academic leaders in Ming Dynasty heard about similar devices.

Based on the known information, Daming is limited to knowing that Britain, France, and Germany have also developed and equipped this electromagnetic wave detector. The specifics are completely unknown, which shows how high the degree of secrecy is.

At the turn of the century, the famous Nikola Tesla believed that electromagnetic waves could be used to detect moving metal objects because of their properties, which was an early theory of radar.

In 7935, the French used a magnetron to generate electromagnetic waves with a wavelength of 16 cm, so that they could detect ships on the sea in foggy days or dark nights, and began to try practical applications.

In the same year, British physicist Sir Robert invented the world's first practical radar device.In the spring of the following year, the construction of the first radar station began on the southern coast of the British main island.

Perhaps in many respects Ming has basically caught up with or approached the world's first-class level, but aero-engine and electronic technology are still weak. From the initial point of view, the electromagnetic wave detector developed by the Ming people is much inferior.

Ever since, in the third meeting with the German Society, the representative of Daming formally proposed the technology of exchanging "electromagnetic wave detectors".

The DB600 liquid-cooled engine is not bad, but the hydrogen oxide torpedo is already considered a black technology, and now it needs radar?
Insatiable!

The Deutsche Society is currently taking three paths in this regard at the same time. Carrier-based aircraft monitoring radar, land-based aircraft monitoring radar, and shooting control radar are generally smooth, but is it right to use this disruptive technology as a bargaining chip? Too outrageous?

The significance of radar is not comparable to "better engines" and "better torpedoes". The tactical advantage that can be obtained by detecting the enemy's attack dozens of kilometers in advance is really huge.

The Deutsche Agency representatives obviously had no right to decide the matter, and the situation was truthfully forwarded to Berlin.

After two and a half days of deliberation, Daming's request was rejected - everything else can be discussed, but the radar is not, or in other words, not yet.

Although the request for direct technical exchanges was rejected, the Germans roughly disclosed the technical performance indicators of the radar they were developing.

As a result, the members of the Electric Detection Research and Development Association deeply realized the huge gap.

Not to mention the British who are at the forefront of the world, the Germans claim that the Americans are now experimenting with 15kW power shipboard radars, and the detection range can reach 80㎞.

However, politics is not a child's play. It is impossible for the imperial court to change its attitude immediately because of the current technology. Since the Germans are not willing to give it, there is no need to ask for it.

Therefore, while continuing to increase support for independent research and development, the intelligence office of the Metropolitan Government also instructed the military attaches of embassies in London, Washington, Paris, and Berlin to focus on collecting all intelligence information about radar.

At the same time, Zhou Changfeng had taken the opportunity to return to the First Marine Regiment in Tokyo.

Saying goodbye to his wife again was no longer as sad as the first time before. He was quite tired from the bumpy flight for several hours, so he went to bed and fell asleep after a quick wash.

But even in the same time zone, there are always many people who need to stay up all night.

76㎞ west of Tokyo, in Otsuki City, Yamanashi Prefecture.

Unlike the coastal areas, the interior of the Dongying Islands is full of mountains. A search team from the [-]th Infantry Regiment of the [-]th Infantry Division of the Ming Army is camping in the mountains.

The day before yesterday, during a routine patrol, an Air Force plane noticed this activity with a small group of soldiers and horses. It was highly suspected that it was a resistance guerrilla. Therefore, the General Military Department ordered the Seventh Division to mobilize some troops and formed several search teams to come to reconnaissance , chase.

The bright moon has just reached the treetops, and the temperature in the mountains is much lower than that in the plains. The wind in the mid-spring night seems a bit cold?

The soldiers built small tents with ponchos, and then wrapped themselves in military blankets and prepared to sleep.

Some people didn't have time to eat because they were standing guard before, but now they have time to fill their stomachs after taking turns.

The canned braised pork that comes with it will be very disgusting if eaten cold, and the sticky and greasy oil is really disgusting, but as long as you heat it up with a campfire, it will immediately become fragrant.

More than 40 people are already resting, and eight or nine people are still chatting quietly while eating, and several officers and non-commissioned officers are discussing the map around the bright gas lamp.

On the periphery, a few soldiers with rifles on their backs are standing guard, which is a clear sentry; there are also those who climbed up trees and hide among the branches, which are called dark sentries.

But a hundred meters away, a large group of figures are slowly approaching...

The rifles they carried had bayonets attached, and the bayonets had been smeared with mud to prevent reflections.

After half an hour.

"Why did a rabbit jump out? It's strange." A private said to the soldier beside him who was smoking.

As soon as his words fell, there was a sudden change!
"assault!"

"Long live!!!"
