Mhammad spoke very seriously, and the people around him listened very seriously, but this thing, which is well said in theory, is another thing when it actually works.

Reverse mapping of Patriot missiles is not so simple. In addition to the technology of the missile itself, it also needs the support of advanced electronic technology.

Sure enough, after Mhammad finished speaking, there was no sound at the scene.

"What? Isn't everyone confident in mapping this missile? Mhammad asked.

"We're afraid we won't be able to draw special people to survey and map now." Mr. Pan said: "Our existing strength, digesting and absorbing other imported technologies, is already a little inadequate, and then mapping a brand-new missile, we also lack the people to take the lead." ”

Mhammad frowned when he heard this, what a shameful thing he said.

"I can try." At this moment, the girl on the side spoke.

Bai Xue followed Mhammad's team, and did not speak all the way, and everyone was curious about the Chinese girl in the green military uniform among the Pakistani guests, translator? No, what kind of person is that?

Until she spoke, everyone was Yileng, this girl, I don't know how thick the sky is, is it so easy to imitate the Patriot missile system?

"Bai Xue, your focus is to continue to improve our fighter radar, which is related to the development of our new fighters in the future." Mhammad said.

Snow white? Mr. Pan's eyes lit up suddenly, it turned out to be Cheng Fei, this girl is not simple, I heard that the most complex flat slit radar was conquered by her.

"We have mastered the technology required for fighter radar, and besides, the 14th Institute has learned all the technologies and handed them over to the 14th Institute to continue to improve, so there should be no problem." Bai Xue said: "President Mhammad. Now, let's map and copy the Patriot missile, which is more meaningful to us, this is a new phased array radar, as well as a variety of processing technologies, to imitate this weapon system. It will have a great promotion effect on us, and I can organize technicians to imitate it. I've gained a lot of experience. ”

When it comes to reverse mapping of American-made radars, Bai Xue has indeed mastered a lot of experience, and now, they can all be used to map Patriot missiles, and there will be fewer detours in this way, and these benefits, Mhammad quickly figured it out. Indeed, the pros outweigh the disadvantages.

It's just that...

"I promise to complete the mission, or we can make another military order." Bai Xue said to Mhammad.

"I'm not worried about that." "The U.S. Patriot missile system has always been closely guarded, and although we can operate it, we are also under the supervision of the Americans, so it is more difficult for us to map and map," Mhammad said. Those who participated in the development had to go to Pakistan. And I estimate that it will take five to ten years for us to be able to thoroughly understand this weapon system and let you go to Pakistan and stay for so long, are you willing? ”

Although it is not yet at the level of later generations that can really intercept ballistic missiles. However, the Patriot weapon system is also the trump card of the US Army, and it is not willing to take it at all, and it is absolutely impossible to transport a set to China, so it can only be quietly mapped and mapped in Pakistan.

Bai Xue's age is not too young. I should also think about getting married or something, I went to Pakistan, where is there such an opportunity, my good youth has been delayed.

"Okay, I'm tired of staying in China anyway." Bai Xue said: "I can accept going to Pakistan. ”

In order to keep secrets, many of them have to remain incognito, and even have to be separated from their families, especially those who make nuclear weapons.

Devoted to the cause of national defense, Bai Xue has long been mentally prepared, her advantages in electronics make her more suitable for this job than others, and she doesn't think there is anything bad about going to Pakistan, where she also likes the environment very much.

Now that Bai Xue has agreed, Mhammad did not continue to refuse, and said: "Then with you as the general leader, draw some forces from your country and our country to form an imitation team and jointly carry out imitation secretly." ”

"Okay." Bai Xue immediately agreed.

"I have another request." After talking about the arrangement just now, Mhammad continued: "The design of the new warship must pay attention to stealth performance. ”

Stealth performance? The word Mhammad stunned everyone when they heard it.

In later generations, stealth was a buzzword, and now, for most people, it's still a very foreign aspect.

But Mhammad knows that stealth has long been noticed by the world powers, and the most technologically advanced is the United States.

At this time, the American F-117, the first stealth attack aircraft, has long been equipped with troops and will show its skills in future wars.

Stealth does not mean disappearing, nor is it invisible to the naked eye. By the time it can be seen with the naked eye, it will already be a distance solved by a rifle.

In modern times, an important means of detection is radar, the so-called stealth, which also refers to the inability to detect each other with radar.

Radar is by emitting electromagnetic waves, encountering the target, returning electromagnetic waves, such a process to detect, if the target shape is special, the return electromagnetic waves are reflected in other directions, can not be received by the antenna, which plays a good stealth effect.

The F-117 is such an idea, its surface is quite peculiar, not even considering aerodynamics, the priority is radar reflection, and the result is a special shape, very sci-fi.

The stealth of the warship not only includes radar, but also sonar and infrared detectors, so the shape of the warship should also be changed, and the inclined or circular design should be adopted, with the freeboard stretched outward and the superstructure tilted inward, so as to achieve the purpose of significantly reducing the radar scattering area.

At the same time, the chimney is a huge infrared heat source, and this effect can be achieved by reducing the temperature of the smoke emitted by the chimney through the special design of guò.

"I'm sorry, President Mhammad, our warship, it's a big guy, considering stealth performance, is it necessary?" A designer asked.

"Of course it's necessary." "If we use simple means, we can greatly reduce the radar reflection area, for example, if the upper part of the island is tilted, we can reflect the radar wave in another direction, even if it is only reduced by half, then, the hull of our destroyer will be used as a frigate by the other side, and at the same time, the distance to discover us will also be greatly reduced, for example, they can find destroyers at a distance of 100 kilometers, then now, they can only be found at a distance of 50 kilometers, this distance, Enough for us to attack them with anti-ship missiles. We don't need to emphasize the stealth performance, as long as we pay a little attention to the design, we can greatly reduce it. ”

Relying too much on stealth will not reach this level for the time being, as long as the stealth factor is taken into account when designing, even if the radar reflection area is reduced by half, then the goal will be achieved.

"Okay, we can think about it." Mr. Pan said.

"On the other hand, it's radar." "I hope that our warships can continue to be equipped with meter-wave radars," Mhammad said. The improvement of the meter-wave radar cannot be abandoned. ”

Meter-wave radar refers to the wavelength of electromagnetic waves used by radar, and now, advanced radars all use shorter centimeter waves, and the shorter the wavelength, the higher the detection accuracy.

The West has long eliminated the meter-wave radar, and you can distinguish it by looking at the skyline, which uses a huge Yagi antenna. And in China, until the Shenzhen ship, there is still such a big guy in the tail.

The accuracy of the meter-wave radar is poor, and it can only see the target, but it cannot accurately know the direction of the target, let alone guide its own missile attack, which is the disadvantage of the meter-wave radar, but the meter-wave radar also has its own advantages.

The meter-wave radar has strong penetrating power, and can still penetrate clouds, fog and rain under adverse weather conditions. For targets in the shadow area of electromagnetic waves behind the occlusion, the meter-wave radar still has a certain detection capability.

Two other advantages are embarrassing and prominent, one is that it can deal with ARM anti-radiation missiles. The seeker of an anti-radiation missile must be able to accurately search and track the target radar, and the antenna caliber of the head must be at least one wavelength larger, and no matter what anti-radiation missile, the diameter of the seeker cannot be one meter long, so it is impossible to deal with the meter-wave radar.

Another advantage is that the meter-wave radar can detect stealth targets, whether it is a wave-absorbing coating or a change in shape, due to the longer wavelength of the meter-wave radar, it can effectively detect stealth aircraft. In later generations, after the air threat was mainly stealth aircraft, the meter-wave radar was still useful.

"The meter-wave radar is the key radar of our warships, and we will not give it up." Mr. Pan said.

Pakistan is advanced in many aspects, especially in terms of military equipment, they have more contact with the West, and now, these opinions put forward by Pakistan are very enlightening to Mr. Pan and others, especially the stealth aspect mentioned, which is worth considering.

At the same time, the mapping of Patriot missiles and the development of a similar Aegis system have played a vital role in the development of their own warships, and Mr. Pan has begun to yearn for this.

Mhammad's trip to the East came to an end again, and when he returned, he brought with him a group of technical experts from the East, who had taken on an even more special mission.

At the same time, on the other side of the world, American technicians are also elated.

After the United States developed the F-15, the Soviets began to develop their own third-generation fighters in a targeted manner, and now, the Soviets' new generation of fighters, Su-27, MiG-29, have begun to equip the Soviet Air Force in large quantities, in Western Europe, the NATO Air Force will engage these fighters at any time, so it is very important to master the performance of these aircraft.
