Qin Tao doesn't understand aerospace, so he can't help much. At most, Qin Tao can only provide some financial support and some chip cooperation.

The chips used on satellites are also very difficult. After all, it is very difficult to protect against cosmic rays in outer space. However, the chips used in receiving terminals on the ground are very simple. They rely on advanced chip technology

, it is completely possible to make cheaper and more durable chips.

After visiting the Beidou system, Qin Tao still felt very complicated.

"Technically speaking, our Beidou-1 is undoubtedly backward. It also requires calculation by the ground receiving station. It takes a long time and the receiver has to transmit signals, which can easily expose the target. However, this is a zero breakthrough after all. From

Starting from nothing, this first step is the most difficult." Mr. Sun's words were still echoing in Qin Tao's mind.

Other satellite navigation systems are all global. They achieve global networking by deploying more than twenty satellites in outer space. No matter where they are, more than three satellite signals can always be received overhead. By receiving satellite signals,

Able to determine one's position.

However, Beidou-1 is a dual-star positioning system. There are only two satellites, so the specific location coordinates cannot be determined. It also requires communication between the ground and the satellite, and then calculation. In this way, if the receiving terminal on the ground emits electromagnetic signals, there is a possibility of exposure.

However, this is only the first generation after all. The problem of presence or absence has been solved first. In the future, the second and third generations will be like the United States and do not need terminals to transmit signals.

"Taozi, a lot of our work in the aerospace field is inseparable from your help." Wu Shengli said with emotion: "For example, the unit next door is studying the project of anti-ship missiles to attack aircraft carriers."

Qin Tao's eyes suddenly lit up: "Dad, can we go and have a look?"

"Of course, I want to see it too."

Qin Tao felt excited in his heart. He had mentioned it many times in the past, and had even helped get Lao Maozi's sample bombs back. However, he had not yet been exposed to the specific project.

This is the first time.

After entering, the first thing you see in the long workshop is a launch vehicle.

The front of the car is a hy472 trailer produced by the domestic Hanyang factory, with a 6*6 chassis and all-wheel drive. The front of the car is a double cab and looks very round. The thing towed behind it looks like a boiler.

It was a cylinder, about ten meters long and one meter sixty-seven meters in diameter. There were various openings on the side of the cylinder, just like the coal loading port of the boiler.

This thing looks unattractive. Even if it is not covered with camouflage nets, people will think it is dragging a boiler when driven out. In fact, this kind of vehicle is currently the most advanced Dongfeng-21 ballistic missile launch vehicle in China!

(Many readers complained about the use of party dues before. In fact, it was to avoid taboos. Now I feel that party dues are probably more dangerous, so I might as well use Dongfeng.)

In the past, there were also Dongfeng-3 missiles that could be launched mobilely. However, this missile was liquid and needed to be filled with fuel before launch, which took a long time. But now, it has been replaced by a solid missile that can be set up at any time.

beat.

"The huge waves come ashore and the east wind blows into the sea." Looking at this big guy, Qin Tao sighed with emotion.

Wu Shengli was a little curious: "Taozi, what do you mean by this? We can understand the first half of the sentence, but what about the second half? Is our Dongfeng going to be on a warship?"

Qin Tao smiled.

There is a theoretical basis for Julang to land. After all, the first solid ballistic missile in China is the Julang-1 missile used on the 092 nuclear submarine. After all, using liquid missiles on nuclear submarines is too complicated, so we might as well do it in one step.

The solid missile came out. After it was built, the superiors were very satisfied. This kind of missile could not only be used at sea, but could also be towed around on land by a trailer.

So, it became a huge wave coming ashore.

However, there is no theoretical basis for Dongfeng to go to sea. From Dongfeng-1 to Dongfeng-5, they are all liquid missiles, which are impossible to install on warships. Only the weird Asan will support them on the helicopter deck of the frigate.

Pick up a ballistic missile and launch it.

As for Dongfeng going to sea, we have to wait for a while. After the Dongfeng-31 missile on land comes out, it will be used by the navy and transformed into the Julang-2 missile.

Now, of course it hasn't started yet.

Facing Wu Shengli's question, Qin Tao could only smile: "The huge waves can come ashore, and the east wind can go to the sea. Dad, just wait and see."

"Lao Wu, why are you free to come to our place?" At this time, Mr. Huang came up to greet him. When he saw the people around Wu Shengli clearly, he was surprised again: "Hey, isn't this Mr. Qin?"

(He is not the same as the person who worked on nuclear submarines before.)

"Mr. Huang, I'm glad to see you. I didn't expect that you are still fighting on the front line at such an old age." Qin Tao stretched out his hand.

The strength of the motherland's national defense cannot be achieved without the silent dedication of a group of scientific researchers.

In the 1940s, Mr. Huang studied in the UK as a graduate student and saw the V-2 missile with his own eyes. At that time, he made up his mind: he must make his own missile!

After returning to China, Huang Lao invested in the research and development of domestic missiles.

In 1960, China's first missile "Dongfeng-1" was successfully test-launched, achieving a breakthrough in China's missile development from scratch.

In 1964, the "Dongfeng 2" came out, and China made great strides in the missile field. However, these are liquid missiles. When facing a preemptive strike by the enemy, they seriously lack survivability and do not have the ability to carry out a second nuclear strike.

Therefore, in 1970, Mr. Huang accepted the task and became the chief designer of the first-generation submarine-launched missile "Julang-1". Twelve years later, the "Julang-1" missile was successfully test-launched in the Bohai Sea, and China became

It is the fifth country in the world to have underwater-launched nuclear missiles, and it has also become one of the few countries in the world to have a second nuclear strike capability.

This is of course just the beginning.

After the success of Julang 1, the country began to carry out the Julang ashore project. After the Julang ashore became the Dongfeng 21, it began to develop the more advanced Dongfeng 31.

The old man in front of me made a huge contribution.

At this time, Huang Lao held Qin Tao's hand tightly: "Mr. Qin, I have wanted to meet you for a long time. On behalf of our scientific research team, thank you for your outstanding contribution to us!"

Qin Tao felt a little embarrassed: "The things I made are all handy and don't deserve such praise."

"No, Mr. Qin, in addition to those missiles, you have something more valuable to us. Have you forgotten that you were assassinated in the capital? After that, you followed the clues and caught the traitor who leaked our latest scientific research secrets!

Thinking about this now, we are still sweating. The project we are currently developing has been betrayed by the traitor! Fortunately, we caught it early and our scientific research results have not been released yet, otherwise..."

What Mr. Huang is talking about is, of course, the matter of Guo Qianjun. This person is the deputy chief designer of the ballistic missile aircraft carrier. It is really infuriating that he was bribed by the other party. Although this guy has been sentenced to death, it is still not enough to vent his anger.

.

"Fortunately, the scientific research results haven't been released yet?" Qin Tao wondered.

"Yes, Mr. Qin, this project was promoted by you, so the relevant departments have also passed the decision, and you are the one who has access to the secrets of this project." Mr. Huang said: "Currently, we are studying this project.

However, there are too many technical problems, and we estimate that it will take another four to five years to achieve a complete breakthrough."

Four or five years? It wouldn’t be needed in 1996!

Qin Tao frowned.

This kind of technology for ballistic missiles to hit aircraft carriers is of course very complicated. Otherwise, the motherland will not become the only country in the world with this capability. Even if Qin Tao gets back a lot of old Maozi's things, the problem is

At that time, Lao Maozi was not completely finalized for service, and it was still a semi-finished product.

"Come on, let's go in and talk. Now, I have taken a back seat. Currently, Mr. Zhang is in charge."

Mr. Huang is over seventy years old, and although he is still energetic, he is getting older after all. Therefore, the more energetic Zhang Zhongfulai has taken charge as the chief designer of the anti-ship ballistic missile.

The Dongfeng-21 used in this weapon system is just a vehicle. The most important thing is the warhead. If it is to hit a moving target, the warhead must have the ability to accurately change orbit and move at any time.

"Last time, Mr. Qin got us Lao Maozi's R-33 warhead. We were deeply inspired. We are currently using a similar biconical structure. However, there are still many problems, such as how to make the warhead accurate.

Lock the target." In the laboratory, everyone saw the double-cone warhead and listened to Zhang Gong's introduction.

"As far as I know, our 14th institute has overcome the difficulty of flat-panel aperture radar. Can we use this kind of radar?"

Qin Tao is a layman in this area, and he can only provide some tentative suggestions.

The radars of fighter planes and the radars of ballistic missile warheads are definitely not the same, but they both observe sea targets, and they are still observing downwards in outer space hundreds of kilometers away. It is said that they should be universally applicable.

The diameter of the Julang-1 missile is 1.4 meters. It is said that a radar with a caliber of more than 700 millimeters can be installed.

"Our missile dives down and sees clutter on the sea. Therefore, the radar needs to be able to eliminate clutter, which requires the pulse Doppler mode." Zhang Gong said: "However, because our missile

The diving speed is very fast, and the surface ship moves very slowly, so there is a high possibility that the pulse Doppler radar may filter out the target as clutter."

Qin Tao was startled when he heard this. Is there such a surprise?

"Actually, the main reason is that our missile is in top-attack mode. When it falls from the top of the target, the lateral speed between the target and our warhead is very small." Seeing Qin Tao's confusion, Zhang Gong continued.

In a confrontation between fighter planes, it doesn't matter if you are discovered by the opponent or even locked. As long as you make a side turn and turn in a direction perpendicular to the enemy, it will be filtered out as clutter, causing it to become unlocked.

The situation we are encountering now is similar to this.

"So, how about using synthetic aperture mode?" Qin Tao asked.

He didn't know much, but he was familiar with the synthetic aperture mode, which used radar signal scanning to eventually form a pattern, thus turning one-dimensional distance imaging into a two-dimensional plane imaging.

When the missile swoops down, what it sees is not a point, but a picture, and then the target is retrieved from this picture. Isn't this enough?

"Yes, Mr. Qin, what we currently plan to use is this synthetic aperture mode. However, we are also facing many technical problems. Whether it is the research and development of equipment or the processing of post-processing data, there are a lot of problems.

.”

The only mature one in China is the Flying Leopard fighter-bomber. The first synthetic aperture experiment on the radar used was already in the late 1990s, and this technology has not yet been thoroughly studied.

Moreover, for the Flying Leopard fighter-bomber, it only needs to display the image. However, it will not work if it is placed on the current anti-ship ballistic missile, because there is no one in the warhead, and the electronic equipment inside is needed to recognize the image and analyze it.

The characteristics of various warships, simply put, also require image recognition and processing technology!

This is even more difficult. Without advanced processors and advanced algorithms, it is simply impossible to complete this task.

"Lao Maozi is more direct and can solve all problems with nuclear bombs." Qin Tao couldn't help but sigh.

Lao Maozi doesn't have this problem, because Lao Maozi has always been inaccurate and not powerful enough. He can directly use nuclear bombs to destroy the target even if it is a few kilometers away from the target.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! But we cannot do it. We have to ensure accurate hits, which is very difficult.

"Currently, our Mingzhou Group has invested in Loongson, a company that specializes in developing processors." Qin Tao said, "Our first product will be a 486-level processor. We hope we can help you."

486 level chip?
