When the car market was still talking about the hot sales of Changan MINI, and they were discussing the introduction of similar models, Cao Yang ushered in a group of unique guests.

Due to the twin-tailed scorpion drone under Daystar Technology Group, as well as Nanshan carbon fiber and Nanshan special steel, Cao Yang has dealt with relevant departments quite a few times.

But the people who came this time were people who had never been in contact with them before.

"Mr. Cao, this is Wu Feng, the general manager of the electric technology group, this is Tang Jian, the director of the N Institute of the electric power department, and this is the ......"

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

This was a bit of a surprise to him.

All the companies in the Nanshan system do not have radar research-related business.

However, as soon as Wu Feng spoke, he probably understood the other party's thoughts.

"Mr. Cao, the stealth performance of your twin-tailed scorpion drone is too good."

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

"It's a good thing, but it's also a very scary thing."

"If on the battlefield, the aircraft of other countries have similar stealth performance, then we have no way to detect them, it will be very troublesome."

"So since last year, our superiors have given us the task of researching a radar that can detect a drone similar to a twin-tailed scorpion."

"But after almost a year of tossing, we didn't come up with a satisfactory result."

"The twin-tailed scorpion drone was developed by you, and you know best about the wave-absorbing performance of stealth materials."

"Coupled with Nanshan Semiconductor's deep technical accumulation in various chips and power components, we want to work with Daystar Technology Group to develop an advanced radar that can detect twin-tailed scorpion drones and even stealth aircraft in other countries."

People who engage in technology don't like to beat around the bush when they speak.

After Wu Feng and Cao Yang briefly exchanged pleasantries for a while, they went directly to the topic.

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

However, every technological breakthrough is obviously not so easy.

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

"For example, the absorbing coatings used in stealth aircraft in the United States mainly absorb 100,000~20,000 MHz microwave radar waves, but cannot absorb meter-wave radar waves with a frequency band of 30~300MHz."

"Although the stealth material performance of our twin-tailed scorpion drone is very good, to a certain extent, it is also the same principle as others."

"If you want to develop an anti-stealth radar, just go directly to the meter-wave radar, right?"

Cao Yang is now very active in the improvement of military-related technology, and the power technology group came to look for cooperation, so he naturally would not refuse.

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

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

In later generations, the radar level of Huaxia improved very quickly, and before Cao Yang was reborn, it was basically no worse than the international advanced level.

But in 2012, the gap was still relatively obvious.

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

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

"Therefore, meter-wave radar has long been abandoned by other countries in favor of more accurate microwave radar."

Tang Jian said a little disappointed beside him.

In his opinion, Cao Yang is completely an axe, and half a bucket of water is ringing.

I don't even know such basic radar common sense.

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

So I opened my mouth and ended up saying nothing.

He wanted to see how Cao Yang would answer the 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 of the world, and the development of meter-wave radar seems to be a historical regression and has no meaning."

"However, we can continuously improve the accuracy of meter-wave radar according to the characteristics of meter-wave, and use modern signal processing methods, high-performance computing, antenna array technology and active phased array to significantly improve the accuracy of measurement and increase the performance of airspace coverage, and finally develop a new generation of three-coordinate radar with high accuracy, in the face of this radar, no aircraft can be stealth."

"If we can achieve this goal, then it can detect and track almost all stealth aircraft, in terms of anti-stealth technology, much stronger than the current microwave radar, making Huaxia a global leader in anti-stealth technology."

Cao Yang gave his answer unhurriedly.

Although it still sounds a little empty, these words also let Wu Feng and Tang Jian know that what Cao Yang just said about engaging in meter-wave radar was not nonsense, but after thinking.

But they clearly do not have confidence in this anti-stealth radar.

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

"But from what we know about the situation at home and abroad, it is still a long way to go to achieve the kind of scenario you said."

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

"What if we use GaN power components?"

Cao Yang directly threw a king bomb out.

This immediately shocked Wu Feng!

"Nanshan Semiconductor is also working on gallium nitride?"

"How's your progress?"

"When will it be possible to achieve large-scale commercial production of gallium nitride?"

Obviously, as a radar expert, Wu Feng is well aware of the importance of gallium nitride, a semiconductor material.

Compared to other semiconductor materials, gallium nitride can transmit higher voltages and is more efficient.

According to the calculations of some foreign publications, gallium nitride materials can increase the power of military radars by 5 times compared with traditional radars, while reducing the volume by half!

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

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

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

Such a thing, the power technology group also has people to study.

However, progress has been very slow.

According to the information that Wu Feng understands, the United States has not yet applied gallium nitride to radar in large quantities, because the relevant technology maturity is not enough.

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

"Mr. Wu, the R&D work of gallium nitride semiconductor of Nanshan Semiconductor has been basically completed, and it 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, so that the power of phased array meter-wave radars will become larger, the detection distance and detection accuracy can be improved, and the cost and volume will decrease."

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

"When the time comes, our anti-stealth phased array meter-wave radar will be officially successful."

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

Gallium nitride has been successfully studied?

Will it be mass-produced within this year?

That's an exaggeration, isn't it?

According to the information he heard, Raytheon, which produces Patriot anti-aircraft missiles in the United States, has invested a lot of money in the research and development of gallium nitride, but it has never succeeded.

Loma is also organizing a large number of people to study these technologies.

Even in 2010, Loma reached Technology Maturity Level 6 and was able to demonstrate a high-power L-band transmitter built with GaN technology.

Loma is also developing GaN technology for X-band radar.

But all these things have not really entered the state of mass production, and they have not yet been equipped with the relevant institutions in the United States.

If Huaxia can break through in advance and replace the TR components on various phased array radars with silicon nitride power components, the meaning behind it will be too great.

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

The significance of this is absolutely extraordinary.

Whether it is an anti-aircraft missile, an aircraft, or a ship, it all needs radar to cooperate with it in order to play its role.

And the gap between advanced radars and backward radars is bigger than the gap between humans and dogs.

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

"Can we take a look at the GaN-related information?"

"Don't worry, we sign a non-disclosure agreement!"

Although Wu Feng felt that Cao Yang did not need to deceive himself, this news was too crucial.

Especially for the power group, it is simply something that will change dramatically.

When the time comes, all the phased array radars they study can be upgraded.

After upgrading, not only the performance is improved, the energy consumption is reduced, the service life is longer, and the cost is also reduced.

This is too important for airborne radars and shipborne radars.

In particular, the current phased array radar is often relatively large, and there are still many restrictions if you want to get it on aircraft and ships.

You're too small to keep up.

It's too big, there's no place for you.

With GaN power components, the situation is completely different.

At that time, there will be a rapid change in the radar technology of the entire Chinese sea, land and air force, and even the technology of related equipment.

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

"Daystar Technology Group wants to cooperate with the Electric Technology Group, and the information of gallium nitride can naturally be shown to Mr. Wu."

"We can even take a tour of the production line that is being planned and see the gallium nitride we produce in the lab."

If you want to engage in radar, it is definitely more appropriate to pull the electric technology group to do it together.

After all, they have accumulated a lot of experience in this area.

However, Cao Yang must also take precautions, so as not to make wedding clothes for people when the time comes.

Although they are all contributing to Huaxia, he is definitely unwilling to do this kind of thing of making wedding clothes for others.

Therefore, even if it is cooperation, everyone must confirm the way of cooperation.

Daystar Technology Group does not do things that suffer losses.

"That's great!"

"Why don't we go now?"

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

As long as this thing is really done, then the anti-stealth phased array meter-wave radar that Cao Yang just said will have strong predictability.

It's perfectly okay to rush hard.

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

We divide the labor of various radars, and after the cooperative research and development, some are produced by Daystar and some are produced by the Electric Technology Group.

……

The signing ceremony of the cooperation between CETC Group and Daystar Technology Group was carried out very suddenly.

Wu Feng: After confirming that Nanshan Semiconductor had really done GaN, they decided to cooperate with Daystar to develop radar without any hesitation.

The new model of anti-stealth phased array meter-wave radar is developed and produced by the personnel arranged by the Electronics Technology N Institute to assist Daystar.

Other models of Star Array radars are developed and produced by semiconductor experts arranged by Daystar in cooperation with CETC.

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

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

It can be used even on AWACS aircraft.

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

In the future, Daystar will also make efforts in the aerospace field, and the research on radar technology is naturally necessary.

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

"I wonder what you think about the use of this semiconductor?"

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

In his opinion, these things of a very obvious nature for military use obviously have to be kept secret at a high level and cannot be sold to other customers.

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

"GaN semiconductors not only have strong application significance in military products, but also have a very promising future in the civilian market."

"After our production line is put into operation, if we only produce a few phased array radars, there will definitely be no way to fully exploit the advantages of production capacity."

"Not to mention the cost of impact, it will also be detrimental to the development of new technologies."

"Only by continuously expanding production capacity, reducing costs, and investing more R&D expenses can we achieve sustainable development of technology."

"Therefore, gallium nitride semiconductors must be developed at the same time by military and civilian, and take the road of military-civilian integration."

Cao Yang gave his reply without any hesitation.

Don't be polite when you should refuse, otherwise there will be a lot of restrictions on Nanshan Semiconductor's side at that time.

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

It's not what Cao Yang wants to see.

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

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

"Or when the time comes, when the whole needs several lines to produce gallium nitride, one of the lines is dedicated to the production of military products."

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

Pan Jun is still doing his best.

And Cao Yang didn't completely say it to death, "If the production capacity can be satisfied, it is naturally possible." ”

"At that time, if we can produce some reduced versions of the foreign trade version of the radar, or if it is loaded on our products and can be sold all over the world, then maybe it is indeed possible to reserve a special production line."

Taking this opportunity, Cao Yang also wanted to give Pan Jun a dozen vaccinations, so that he would know that many of the products produced by Daystar ultimately hope to make money in the international market.

Otherwise, it will be sold to the relevant domestic departments at a very low profit every time, and this kind of business will definitely not last.

Obviously, the arms business is all profiteering, but Daystar is just making some hard-earned money.

This is not the outcome that Cao Yang wants to see.

"I can't answer you right now, but it's definitely a possibility."

"Although we are not a major arms exporter, we will definitely be taken seriously in this area of business in the future."

"If Daystar can find some customers on its own, and the relevant products sold are specially produced foreign trade versions, I think the possibility of approval is still very high."

"After all, the relevant departments are now attaching great importance to civil-military integration projects and will give more support policies."

Pan Jun can't do the main thing himself, so naturally he doesn't dare to agree casually, otherwise he will be embarrassed if he can't get off the stage at that time.

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

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

In the future, when you really need to export, you can just put it up separately.

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

Daystar Technology Group is the most important group in 2012.

In this case, he must personally participate in the most important overseas event after the establishment of Daystar.

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

Whether Daystar's first shot overseas can be fired smoothly depends on the performance of a few days.
