Rebirth 99 to become a car giant

While the auto market was still buzzing about the hot sales of Changan MINI and everyone was discussing the introduction of similar models, Cao Yang ushered in a unique group of customers.

Due to the Double-tailed Scorpion drone under the Venus Technology Group and Nanshan Carbon Fiber and Nanshan Special Steel, Cao Yang had to deal with relevant departments a lot.

But the people who came this time were people I had never interacted with before.

"Mr. Cao, this is General Manager Wu Feng of Electronic Technology Group, this is Tang Jian, director of N Institute of Electronic Technology, and this is..."

With Pan Jun's introduction, Cao Yang also knew that those who came to communicate today were experts in charge of radar research.

This actually made him feel a little surprised.

All companies in the Nanshan System have no radar research-related business.

However, as soon as Wu Feng opened his mouth, he roughly understood what the other person was thinking.

"Mr. Cao, the stealth performance of your Scorpion drone is great."

"Although it is not a completely stealth fighter in terms of the structure of the fuselage, due to its small size and excellent stealth material absorption performance, it is difficult for our radar stations everywhere to detect its existence."

"Although this is a good thing, it is also a very scary thing."

"If on the battlefield, other countries' aircraft have similar stealth performance, then we will be in trouble if we have no way to detect them."

"So since last year, our superiors have given us a task to research a radar that can detect drones similar to the Scorpion."

"But after almost a year of hard work, we still haven't come up with satisfactory results."

"The Twin-tailed Scorpion UAV was developed by you, and you know best the absorbing properties of stealth materials."

“Coupled with Nanshan Semiconductor’s deep technological accumulation in various chips and power components, we want to work with Daystar Technology Group to develop a device that can detect Scorpion drones and even detect stealth aircraft from other countries. advanced radar."

Technical people don't like to mince words when talking.

After Wu Feng and Cao Yang exchanged simple greetings for a moment, they went directly to the topic.

The importance of radar technology in modern times is undoubted. As one of the most important radar research institutions in China, the N Institute of Electronic Science and Technology of China has a very heavy task.

However, every technological breakthrough is obviously not that easy.

"Today's radars are basically ultra-short wave and microwave band radars. The main performance of various stealth materials is also based on the absorption performance of this band to measure their stealth performance."

"For example, the absorbing coating used in American stealth aircraft mainly absorbs microwave radar waves in the 100,000 to 20,000 MHz frequency range, but cannot absorb meter-wave radar waves in the 30 to 300 MHz frequency band."

"Although the stealth material of our Scorpion drone is very good, it still uses the same principle as others to a certain extent."

"If you want to develop anti-stealth radar, just use meter-wave radar, right?"

Cao Yang is now very active in improving military-related technologies. If the Electronic Technology Group comes to look for cooperation, he will naturally not refuse.

This is a good opportunity to enhance Daystar Technology Group’s influence in the military industry.

The most important thing is that Cao Yang can really help the other party.

In later generations, China's radar level improved very quickly. Before Cao Yang was reborn, it was basically no worse than the international advanced level.

But in 2012, the gap was still quite obvious.

Especially in research on anti-stealth radar, the gap is even greater.

"The wavelength of meter-wave radar is too long, and it has shortcomings such as poor measurement accuracy and the inability to accurately calculate the target position."

"Therefore, meter-wave radar has long been abandoned by other countries and replaced by microwave radar with higher accuracy."

Tang Jian said beside him a little disappointed.

In his opinion, Cao Yang was just doing what he was doing, and the half-filled bucket of water made a clanging sound.

He actually doesn't even know such basic radar knowledge.

Wu Feng originally wanted to stop the outspoken Tang Jian, but he also felt that Cao Yang's proposal seemed a bit unreliable.

So I opened my mouth, but in the end, nothing was said.

He wanted to see how Cao Yang would answer this question.

If the other party's answer is too unsatisfactory, then he probably has little confidence in this visit.

"Director Tang is right. High-precision microwave radar has become the mainstream in the world. Further development of meter-wave radar seems to be a historical step back and has little meaning."

"But we can continuously improve the accuracy of meter-wave radar based on the characteristics of meter-waves, and use modern signal processing methods, high-performance computing, antenna array technology and active phased arrays to significantly improve height measurement accuracy and increase airspace coverage performance. Finally, Develop a new generation of three-coordinate radar with higher accuracy. No aircraft can be invisible in front of this radar."

"If we can achieve this goal, it will be able to detect and track almost all stealth aircraft. In terms of anti-stealth technology, it will be much stronger than current microwave radars, making China a global leader in anti-stealth technology."

Cao Yang gave his answer calmly.

Although it still sounded a bit empty, these words also let Wu Feng and Tang Jian know that what Cao Yang just said about building a meter wave radar was not nonsense, but had been thought through.

But they obviously have no confidence in this anti-stealth radar.

"Theoretically, what you said, Mr. Cao, is not impossible."

"But judging from what we know about the situation at home and abroad, it is still far away from reaching the vision you mentioned."

The atmosphere at the scene was silent for a moment, and Wu Feng broke the silence.

“What if we used gallium nitride power components?”

Cao Yang directly threw a king bomb.

This immediately shocked Wu Feng!

"Nanshan Semiconductor is also researching gallium nitride?"

"How's your progress going?"

“Approximately when will it be possible to achieve large-scale commercial production of gallium nitride?”

Obviously, as a radar expert, Wu Feng is very aware of the importance of semiconductor materials such as gallium nitride.

Compared with other semiconductor materials, gallium nitride can transmit higher voltages and with higher efficiency.

According to some papers in foreign publications, gallium nitride materials can increase the power of military radars by five times compared with traditional radars, while reducing the volume by half!

The most important thing is that the cost can be reduced significantly.

The research and application of gallium nitride materials is currently the forefront and hot spot of global semiconductor research. It is a new semiconductor material for the development of microelectronic devices and optoelectronic devices. Together with silicon carbide, diamond and other semiconductor materials, it is known as the successor to the first generation of semiconductor materials. The third generation semiconductor materials after germanium, silicon semiconductor materials, second generation gallium arsenide, and indium phosphide compound semiconductor materials.

Even gallium nitride can be said to be the core material of the third generation semiconductor.

The Electronic Technology Group has also arranged for people to study such a thing.

However, related progress has been very slow.

According to the information Wu Feng learned, the United States has not yet widely used gallium nitride in radars because the related technology is not mature enough.

Now that Cao Yang suddenly mentioned gallium nitride, he naturally had a lot more expectations.

"Mr. Wu, Nanshan Semiconductor's gallium nitride semiconductor research and development work has been basically completed and is currently preparing for large-scale mass production."

"According to our plan, the production line can be officially completed this year and put into mass production."

"At that time, these gallium nitride semiconductors can be used in phased array radars, making the phased array meter-wave radar more powerful, improving the detection range and detection accuracy, while reducing the cost and volume."

"At the same time, we have arranged a dedicated team to improve signal processing technology so that the accuracy of phased array meter-wave radar can reach the level of millimeter-wave radar."

"At that time, our anti-stealth phased array meter-wave radar will be officially successful."

Cao Yang revealed a lot of information to Wu Feng in one breath.

Gallium nitride has actually been successfully researched?

Can it be produced within this year?

This is too exaggerated!

According to the news he heard, Raytheon Company in the United States, which produces Patriot air defense missiles, has invested a lot of money in the development of gallium nitride, but has never been successful.

Lockheed Martin is also organizing a large number of manpower to study these technologies.

Even in 2010, Lockheed Martin reached Technology Readiness Level 6 and was able to demonstrate a high-power L-band transmitter built with gallium nitride technology.

Lockheed Martin is also developing gallium nitride technology for X-band radar applications.

However, all of these things have not yet truly entered mass production, and have not yet been equipped with relevant American institutions.

If China can make a breakthrough in advance and replace all TR components on various phased array radars with silicon nitride power components, the significance behind it will be really great.

It can be said that China's radar technology has caught up with or even surpassed the international mainstream level in one day.

This meaning is absolutely extraordinary.

Whether it is anti-aircraft missiles, aircraft, or ships, radars must be used in conjunction to play their role.

The gap between advanced radar and backward radar is larger than the gap between humans and dogs.

"Mr. Cao...I..."

"Can we take a look at some information on gallium nitride?"

"Don't worry, we'll sign a confidentiality agreement!"

Although Wu Feng felt that there was no need for Cao Yang to deceive him, this news was too crucial.

Especially for Dianke Group, things are going to undergo earth-shaking changes.

By then, all the phased array radars they are researching can be upgraded.

After the upgrade, not only the performance is improved, the energy consumption is reduced, the life is longer, but the cost is also reduced.

This is really important for airborne radar and shipborne radar.

In particular, current phased array radars are often relatively large in size, and there are still many restrictions on how to install them on aircraft and ships.

You made it too small and the performance can't keep up.

You have made it too big and there is no place for you to put it.

After using gallium nitride power components, the situation is completely different.

By then, China's entire sea, land, and air radar technology and even related equipment technology will have undergone rapid changes.

In this case, Wu Feng must not be too cautious.

"Venture Technology Group wants to cooperate with Dianke Group, so the information on gallium nitride can naturally be shown to Mr. Wu."

"We can even visit the production lines that are being planned and built, and take a look at the gallium nitride we produce in the laboratory."

If we want to develop radar, it is definitely more appropriate to bring the Electronic Science and Technology Group together to do it.

After all, they have accumulated rich experience in this area.

But Cao Yang definitely wanted to take precautions to avoid making wedding clothes for others.

Although they are all making contributions to China, he is definitely not willing to do this kind of thing like making wedding clothes for others.

So even if it is cooperation, everyone must confirm the cooperation method.

Daystar Technology Group does not suffer losses.

"It would be great!"

"How about we go now?"

Wu Feng couldn't wait to confirm the situation of gallium nitride first.

As long as this thing is really solved, the anti-stealth phased array meter-wave radar just mentioned by Cao Yang will be very predictable.

It's totally okay to try and rush through it.

Of course, in order to avoid risks to a greater extent, Wu Feng felt that this project could be left to Venus Aerospace to take the lead, and the N Institute of Electronic Science and Technology could cooperate.

We have divided the labor for various radars. After cooperative research and development, some are produced by Daystar and some are produced by Dianke Group.

…

The cooperation signing ceremony between Dianke Group and Daystar Technology Group took place very suddenly.

After Wu Feng and others confirmed that Nanshan Semiconductor had really mastered gallium nitride, they decided to cooperate with Daystar to develop radar without any hesitation.

The new model of anti-stealth phased array meter-wave radar was developed and produced by the N Institute of Electronic Science and Technology to assist Daystar.

Other types of star array radars are developed and produced by Venus’ semiconductor experts in cooperation with Dianke Group.

Although it seems that Daystar has received few projects, this field is very promising.

Even after it is completed, it can not only be used as a road-based radar, but can also be installed on ships.

It can even be used on early warning aircraft.

Therefore, this model is obviously very good as an entry point for Daystar Aerospace in the radar industry.

In the future, Venus will also make efforts in the aerospace field, so research on radar technology will naturally become necessary.

"Mr. Cao, I believe you are also very aware of the importance of gallium nitride."

"I don't know what you think about the use of this kind of semiconductor?"

After Wu Feng and his party left, representative Pan Jun couldn't help but confirm some information with Cao Yang.

In his opinion, these items with very obvious military uses obviously require a high level of confidentiality and cannot be sold to other customers.

But Daystar Technology Group is only a private enterprise after all, and he is not suitable to give orders directly.

"Semiconductors such as gallium nitride not only have strong application significance in military products, but are also very promising in the civilian market."

"After our production line is put into production, if we only produce a few phased array radars, we will definitely not be able to fully utilize our production capacity advantages."

"Not only will it affect costs, it will also be detrimental to the development of new technologies."

"Only by continuously expanding production capacity, reducing costs, and investing more in research and development can technology achieve sustainable development."

"So gallium nitride semiconductors must be developed simultaneously by the military and civilians and take the path of military-civilian integration."

Cao Yang gave his reply without any hesitation.

Don't be polite when you refuse, otherwise Nanshan Semiconductor will be subject to many restrictions.

This is definitely not a good thing for the development of Nanshan Semiconductor.

This is not what Cao Yang wants to see.

So even if Pan Jun's starting point was very good, Cao Yang would not agree.

Fortunately, Pan Jun didn't mind, and just added: "Can there be some difference in performance between military-grade gallium nitride and civilian-grade gallium nitride?"

"Or when the time comes when several lines are needed to produce gallium nitride, one of the lines will be dedicated to producing military products."

"Once the radar produced using this material is put into use and proves to be very successful, the demand in the military industry will actually not be small."

Pan Jun is still doing his best.

But Cao Yang didn't completely put his words to death, "If the production capacity can be met, it will certainly be possible."

"If by then we can produce some reduced-spec versions of foreign trade radars, or if they can be installed on our products and sold around the world, then maybe we can set aside a dedicated production line."

Taking this opportunity, Cao Yang also wanted to inoculate Pan Jun and let him know that many of the products produced by Daystar ultimately hope to make money in the international market.

Otherwise, if we sell it to relevant domestic departments at very low profits every time, this kind of business will definitely not last long.

Obviously, the arms business is very profitable, but in the end, Venus is just making some hard-earned money.

This is not the result Cao Yang wants to see.

"I can't answer you right now, but there is definitely a possibility."

"Although we are not a major arms exporter, this business will definitely receive attention in the future."

"If Daystar can find some customers on its own, and the related products it sells are specially produced for foreign trade, I think the possibility of being approved is still very high."

"After all, relevant departments now attach great importance to military-civilian integration projects and will provide more supporting policies."

Pan Jun naturally didn't dare to agree to something that he couldn't take charge of, otherwise he would be embarrassed if he couldn't step down when the time came.

Fortunately, Cao Yang didn't expect him to give an answer right away.

Now it's just a matter of getting vaccinated first.

When you really need to export in the future, just mention it separately.

After the two reached a consensus on this matter, Cao Yang had no time to talk to Pan Jun.

Venus Technology Group was the group that Cao Yang paid most attention to in 2012.

In this case, he must personally attend Daystar's most important overseas event since its establishment.

Li Shigui and others were already waiting in the conference room to report to Cao Yang.

Whether Daystar's first shot overseas can be successfully launched depends on its performance in a few days.
