Genius is just the threshold for me!

On the screen, the image is rapidly shifting eastward.

Soon, pictures of mountains and rivers appeared on the screen, including the suburbs of Chengdu, Longpan Mountain (where we went on our last outing), Ziyang, and other areas.

Today's weather wasn't very cloudy, it wasn't dark yet, and the altitude was only 2 meters.

At this point, the image is mainly provided by a high-precision visible light camera, while synthetic aperture radar mainly provides an auxiliary function for focusing and distance identification.

"The algorithm is fine."

"There are some minor parameters that still need improvement."

Lin Dong moved the mouse to pause and zoom in on the reconnaissance image, carefully observed it for a while, and then opened the corresponding data stream.

After comparing and checking the data, enter the access password to access the system parameter interface and begin adjusting some reconnaissance parameters.

The reconnaissance images from a reconnaissance aircraft are somewhat like the multi-camera modules of a mobile phone a decade or so from now. The camera hardware is very important, but algorithm tuning is also very important.

The same lens, but different algorithms and adjustments, can result in vastly different image quality.

Of course, the phone settings are adjusted to look good and create a specific shooting atmosphere.

The reconnaissance aircraft is being tuned towards greater realism and clarity; only when the images are sufficiently realistic and clear can the reconnaissance aircraft fulfill its true reconnaissance role…

In less than a minute, Lin Dong adjusted the relevant parameters and pressed the Enter key.

Di-

The entire image froze.

A few seconds later, the image was updated, and a clearer image appeared.

"Lin Dong!"

At that moment, Xu Qingling seemed to see something, her pupils contracted, and she pointed nervously at the image that had just flashed by, saying, "Look there!"

"this……"

Lin Dong paused and zoomed in, looking at an airfield hidden in the southwestern mountains. He could clearly see some vaguely visible combat personnel, radar equipment, and various aircraft. A hint of embarrassment crossed his face: "This map scanner hasn't even found the aircraft carrier yet, and it's already scanning out friendly forces?"

"Have we messed up?"

Xu Qingling looked at the airport roof, ground, and aircraft, where the resolution wasn't very clear, but she could still make out the various camouflage nets and camouflage cloths. Her hands instinctively grabbed Lin Dong's clothes, and her expression became even more tense.

As a family member of someone working in the military-industrial complex, she knew some things.

An airport hidden deep in the mountains and forests, with such a well-concealed design, is clearly a highly classified military airfield.

But they just scanned this kind of airport directly...

"We reported it, and headquarters approved it. What kind of trouble have we gotten ourselves into...?"

Lin Dong chuckled twice to reassure her, then picked up the sunflower seeds Xu Qingling had peeled, poured some out, chewed them a couple of times, savoring the rich, oily aroma, and a relaxed, satisfied smile appeared on his face. He also shared some with Xu Qingling.

The headquarters must be aware of the map scanner's reconnaissance capabilities, since the entire reconnaissance aircraft requirement was issued by headquarters.

Wang Xingguo's message urging him to take off suggests he must have anticipated this.

Perhaps this reconnaissance flight of the Mapsweeper has become a special kind of covert training exercise.

Xu Qingling breathed a sigh of relief upon hearing that she hadn't caused any trouble. She took the sunflower seeds Lin Dong handed her and looked at the camouflaged radar antenna on the image, asking in confusion, "Didn't they know they were being scanned by radar?"

"They won't know."

Lin Dong explained simply: "The scanner is equipped with synthetic aperture radar, making it almost impossible to detect."

As for the infrared signal that breaks through the thermal barrier, this is not an infrared radar, and it's highly likely that it's not powered on...

Not every radar can detect and identify the target it scans.

If classified according to the difficulty of sensing, modern radar can be divided into five levels.

The easiest to detect is the traditional mechanical rotating radar, which is essentially a high-powered searchlight. Because the rotating scan has a fixed frequency cycle, the radar warning receiver (RWR) can easily identify it.

The second is tracking radar, which emits continuous bands in one direction. The illuminated radar is easy to detect, but it is difficult to detect if it is not at the illumination angle.

The third is the three-dimensional coordinate radar. Through the combination of mechanical rotation and electronic beam jumping, the enemy can sense the radar scan, but because the beam is constantly jumping, they can only sense it but cannot determine the distance.

The fourth category is the active phased array radar carried by fifth-generation fighter jets such as the J-20. This type of radar can perform beam scanning in just one to two milliseconds by switching the transmitting unit.

Because the scan time is extremely short, the rwr can only sense extremely weak fluctuations. Unless it is a long-term continuous scan with the signal accumulating, it is impossible to detect them.

This radar is also one of the core technologies that enables fifth-generation fighter jets to conduct beyond-visual-range combat, allowing the enemy to be locked on without their knowledge and then hit by missiles.

Finally, there are low-intercept (LPI) spaceborne radars and synthetic aperture radars carried by reconnaissance aircraft.

LPI uses spread spectrum technology to spread out the radar beam, directly hiding it in the natural spectrum.

These two types of radar are virtually impossible to detect with current technology.

Even if it is discovered in the end, it can only be done by analyzing the massive amount of data bit by bit to find the repeated radar features and finally confirm that you were photographed at that time.

But that's at least a week, two weeks, or even several months from now.

Meanwhile, Lin Dong and Xu Qingling were testing the reconnaissance capabilities of the map scanner as they headed towards the South China Sea and the East China Sea.

The core of the Chengdu Aircraft Industry Group (CAC) base, Wang Xingguo's office.

Xu Ziming and Wang Xingguo watched as the screen kept moving and refreshing, occasionally illuminating a reconnaissance view of a hidden location.

When the reconnaissance system finally spotted a log transport vehicle deep in the mountains being swept away, it automatically identified this highly sensitive target and then automatically took a screenshot and zoomed in...

Xu Ziming could no longer maintain his composure and turned to look at Wang Xingguo on the other side.

"Are you just going to let him run wild like this?"

"What's there to be afraid of?"

When Wang Xingguo saw this convoy of logs, his heart skipped a beat.

But he remained calm on the surface, picked up his teacup, took a sip, and said: "The core communication link of Beidou is top secret and does not pass through any external network or low-security channels in the middle."

The raw data transmitted back by the reconnaissance aircraft was specially encrypted by that kid, and could only be decrypted and processed using a decryption module burned into the ground hardware.

"If that kid hadn't given us access to his lab, we wouldn't have seen this footage. There was no risk of leaks, so we just watched it."

He had previously seen Lin Dong add an encryption algorithm to the data transmitted back by the WZ-8, so that all data had to be decrypted by ground hardware before it could be processed and viewed.

At the time, he was still marveling at how the kid's thinking was becoming more and more comprehensive, and his awareness of confidentiality had improved.

Now it seems that this kid probably wanted to fly this reconnaissance plane around taking pictures for a long time.

However, fearing that a problem with the intermediate communication link might expose the reconnaissance operation, they simply encrypted the intermediate data.

This way, even if there's a problem with the intermediate link, outsiders will only see a bunch of encrypted data...

"..."

Xu Ziming was completely convinced and gave a thumbs up, saying, "Is this how you treat the principle of confidentiality?"

"Do you think I want this?"

Wang Xingguo put down his cup, looked at the log transport truck on the screen being covered, and the reconnaissance footage that was advancing and refreshing again at more than 1 kilometer per second. He sighed deeply.

"He's my ancestor now, I have to call him godfather."

God knows.

He had just called his superior to report that Lin Dong wanted to fly a WZ-8 reconnaissance aircraft out to find an aircraft carrier.

At the time, he was worried that the leaders might not be aware of the situation or the performance of the WZ-8, so he gave a brief introduction.

Unexpectedly, after a two-second pause, the leader smiled and praised Chengdu Aircraft Industry Group, saying that the reconnaissance aircraft was very well developed.

As for Lin Dong's trip to find the aircraft carrier, it can be summarized in five sentences.

—I hope he's still just a thirteen-year-old boy, and we won't treat him like old men, stifling his interests and hobbies.

As long as the general direction is good, everything else is minor, after all, it's just taking a photo and visiting.

Like you said, they most likely won't find out. Report any good news promptly.

If we are discovered, it's not a big deal. We can just play our cards in advance. As long as we don't make a move or cross the line, they can sail on the high seas, and we can fly airplanes.

As for what we see on the road, we can treat it as a reconnaissance and leak training exercise. We just need to report where we've exposed something and make improvements accordingly...

In this regard.

What else could he say? What could he possibly say?

It can only be said that in the eyes of the leaders, Lin Dong was treated like that code name of hope, and they placed great hopes on him.

In order not to interfere with Lin Dong's interests or hobbies, and not to affect Lin Dong's potential, they were prepared to reveal the situation in advance and make their moves ahead of time.

All I can say is that this is Lin Dong's status; he's just basking in his coattails.

"When they go back later, tell Xiao Dong what to do."

Thinking of this, Wang Xingguo looked at Xu Ziming and said, "Have him organize all the airports and transport vehicles that we swept up today. I will personally report to headquarters next month at a meeting to promote improvements."

It now appears that our current camouflage technology is effective against space reconnaissance satellites.

However, there is still no way to defend against such a high-performance high-altitude reconnaissance aircraft.

Our WZ-8 is only a medium-sized reconnaissance aircraft, and its performance is inferior to their large SR-72 reconnaissance aircraft, which uses scramjet propulsion.

If they finish building this thing, they can sneak over the line and fly it around.

Hypersonic cruise could expose the entire region's layout in less than twenty minutes... We still need to strengthen our defenses against this.

"..."

Xu Ziming frowned, realizing that this was indeed a potential problem.

But the next second, he realized something was wrong, his eyes widened, and he said, "Why didn't you tell this kid? You've been the one arranging this all along, and the chief engineer of the reconnaissance aircraft is still named after you."

"It's very simple, just say it's more convenient."

Wang Xingguo picked up his teacup, took a sip, and said casually, "Engineer Lin is away on a business trip today dealing with the mechanical dog issue. Engineer Zhang's logistics department has a batch of material purchases that require overtime verification. If all goes well, Xiao Dong will be coming to your house for dinner tonight..."

"I!"

Xu Ziming gritted his teeth twice.

"Stop talking about me, look at the reconnaissance map, we're heading out to sea after reaching Guangdong Province..."

Wang Xingguo's gaze fell on a corner of the ocean revealed in the reconnaissance footage, a hint of emotion on his face: "Cruising at Mach 4, this thing is twelve meters long, and it traveled from Chengdu to the coastline of Guangdong Province in less than seventeen minutes. It's really insane..."
