"Second question." Of course, Qin Xue will not give him time to think about it, interrogating the prisoner is also a series of cannons, and not giving the prisoner a chance to think is just to make the prisoner have no time to think about it, and there will be a flaw.

"In the processor of radar, the single-sideband filter is an important component, this component filters out a single spectral line from the echo spectrum, and the signal power is reduced by D square times, this D is the duty cycle, but at the same time the clutter and noise power are also reduced, so theoretically, it will not reduce the signal-to-noise ratio, but in the actual manufacturing process, it still causes a great decline, what technical means should be used to overcome this?"

This question is more professional than the one just now, this is a technical problem with a certain component in the radar, this problem, Ramour really won't, now, he thought for a while, and then, shook his head: "I didn't expect that I was so old, and I was still teased by your little girl, Ward, come and solve the siege for me." ”

It can't be two people to eat, there are ten people sitting around this table, just now Qin Feng has been chatting with Lamour, the others are eating, and they don't pay attention to them, now, seeing that Lamor is about to be embarrassed, he began to call for support.

Hearing his words, the man called Ward raised his head: "Ramour, haven't you always been very good?" Hit the nail this time, right? A steak. ”

Ward is asking for a favor with Lamour, invite me to a steak, and I will solve this matter for you, this kind of communication between the two is in Hebrew, Qin Feng and Qin Xue can't understand it, but it can be seen that they must be good friends.

"You must have encountered a lot of problems in the process of researching the radar, right?" After negotiating the price with Ramour, Ward began to communicate with Qin Xue in English.

The other party has already said it through, Qin Xue can only admit it, but if Qin Xue directly says that she has encountered problems, it will be too underestimated Qin Xue's IQ and EQ, her words changed: "Your research and development in radar is worth learning from us, just like this Mr. Lamour, my brother's teacher, they are all test pilots, and you, also our teacher, we are very envious of your achievements, you have developed from a simple ranging radar to the current pulse Doppler radar, The road traveled is admirable. ”

Qin Xue will also be a sycophant, Qin Feng secretly thought in his heart, this sister of his own, it is really difficult for her, but after saying this, the other party is really happy.

"yes." Ward said: "Back then, we could only make the EL/M-2001B ranging radar, and on the basis of this radar, we finally came up with the EL/M2021 multifunctional combat radar after repeated research. It is this radar that is now installed on our Cub fighters. ”

The emergence of this kind of radar has finally made them a big country in the research and development of airborne radar, and even their radar performance is better than that of Europe, after all, they are close to the water, and they can directly purchase the most advanced military integrated circuits from the United States.

Although the antenna also uses an inverted card antenna, it relies on the advanced digital processing system to achieve a lot of functions, air-to-air, search, automatic tracking, air interception, short-range combat, etc., as for the air-to-ground aspect, there are air-ground ranging, air-to-ground bombing, air-to-ground shooting, terrain tracking, ground object avoidance, terrain mapping, navigation, etc., it can be said that the function of a modern radar should be fully realized.

Ward said that he was better than Ramour just now, and the research and development of the whole system one by one, including transmitters, processors, modulators, missile irradiators, radio frequency heads, weapon delivery units, receivers, radio frequency exciters, servo amplifier units, power supplies, interface computer units and missile delivery computer units, etc., what problems have been encountered and how to overcome them, this continues, even the lunch break time has to pass.

Other people have left one after another, and everyone has the habit of taking a nap, and the Chinese delegation here did not leave, nor did they come up, and they knew that what they were talking about now was of great enlightening significance to their own side.

It's absolutely impossible to get the other party to teach you by hand, and now the other party says that the history of the original research and development can already get a lot of useful information from it.

Qin Xue listened very seriously, she didn't have time to take notes, so she could only memorize these things in her mind first, and then slowly repeat them later.

"It's a pity that if this radar uses a flat slot antenna, the performance will be more powerful." Qin Xue couldn't help but sigh after listening to what the other party said.

Qin Xue said this, of course, he continued to set the other party's words, this old engineer obviously regarded Qin Xue as the object of confiding, since he said it, then simply say enough, after all, according to the plan of their inspection team, it was originally to show them the LAVI fighter jet, since the fighter can be displayed, the supporting radar can also be slightly revealed.

Of course, Ward is not completely open-mouthed, and when he meets a smart apprentice, he can't wait to tell him all his knowledge, and he actually has his purpose in saying this.

After all, for Israel, if the military industry wants to develop, it has to be sold, and they don't care how advanced they are, whether it will bring any danger to themselves, as long as they can make money.

They have already sold missiles to China, and if China needs it, they can sell these radars to China at any time, and now he introduces them so that he can also interest the Chinese, and then sell the radar to them.

Otherwise, even if Ward is in high spirits, it is impossible for him to say a lot of things without scruples. He took the opportunity of Qin Xue's question to show the Chinese their radar, in case it was sold!

"For the new fighter, we have also developed a matching radar. Codenamed EL/M-2035 multi-purpose fire control radar, compared with the current 2021 radar, in addition to the replacement of a new flat slot radar antenna, the electronic system behind it has also undergone large-scale replacement, such as the use of programmable signal processors, distributed data processors and other new technologies, which comprehensively improve the performance of air and ground detection, and at the same time, the original radar mode has also increased a lot, such as searching and ranging, searching and tracking, etc., In the air-to-ground mode, real beam drawing and screen freezing and expansion have been added; Doppler beam sharpening, ground moving target designation, and other modes. It had already reached the first-class level of airborne radars in the world at that time. Compared with the radar of the United States, it is not inferior. ”

Ward said this, proudly.

After all, the 2021 radar was finalized in 1977, and it has not been completely changed after several upgrades, and now in 2035, it is a reborn change!
