Of course, it is difficult to find someone Chen Fei asked for. Even an internationally renowned university like Capital University, it is not easy to find such a teacher. You can only do it slowly and be anxious and can't eat hot tofu.

Yu Hua was working hard to find Teacher Yueyu, while Chen Fei was looking for Teacher Yueyu, three uninvited guests suddenly found Chen Fei.

The leader is Zhao Jiayu, and the other two are researchers from the Academy of Military Sciences. However, they are in their seventies, but they are in good spirits and look great. They walk wildly, and ordinary young people really can't catch up.

"Chen Fei, let me introduce you to me. This is my uncle Zhao Chenggong, my uncle's colleague, Professor Huang Lihua, and a researcher at the Academy of Military Sciences."

Zhao Jiayu did not introduce more things, but Chen Fei could guess that these two old men should not be that simple, at least they are big shots in their respective fields.

"Hello, Mr. Zhao, Mr. Huang!" Chen Fei hurriedly shook hands with them.

"Xiao Chen, I have wanted to see you for a long time. You know this, right? Unfortunately, we have been making mistakes by mistake. Either you have something to do or I have something to do. Now... Haha, we finally see the above, it's not easy!"

Zhao Chenggong was very talkative, talking nonstop, and laughing very much. He laughed loudly, nodded and smiled, sometimes burst out laughing, sometimes laughing brightly, giving people a very friendly feeling and it was very comfortable to get along with.

But the other one, who is named Huang Lihua, is not so talkative, but it is not intentional. It should be due to his personality. He is introverted and doesn't talk much. Compared to speaking, he seems to like thinking more.

After a few greetings, Zhao Chenggong said: "Xiao Chen, we are here to find you today because we want to talk to you. I want to talk to you about the prop gun you made in the TV series last time. Where is Lao Huang, he wants to talk to you about the radar you mentioned a few days ago."

Zhao Chenggong briefly introduced his meaning.

"I'll do it first." Huang Lihua, who had been silent all the time, suddenly spoke, looking a little impatient.

The things Chen Fei said at the premiere of "Island" last time were recorded by several military enthusiasts and uploaded to the Internet.

His speech well explained what a war situation is - even his own people are fooling each other.

Some of the things he said are based on facts, some based on things in memory, and some, the proportion of this part is slightly larger, which is a bit of a mess and a nonsense.

So what he said is true and false, the facts are false, but the theory is true, and even his own people will be confused, let alone the enemy.

Huang Lihua asked directly without any detours: "What's going on with the detection of the distance expansion target you mentioned last time?"

Um?

Chen Fei was stunned for a moment, and his eyes couldn't help but look at Huang Lihua.

This old man is worthy of being from the Academy of Military Sciences. He can actually find the most critical thing from his messy conversations.

After listening to Huang Lihua's question, Chen Fei pondered it for a while, and then explained: "Old Huang, then I will tell you my own understanding, but I am not a major in this area. I am just thinking about it. If it is wrong, don't care.

I think so. In high-distance resolution radar, the echoes of each scattering center of the target are separated in the time domain, which provides an important prerequisite for accumulating the echo energy of each scattering point and improving the radar's detection ability of the target."

Speaking of this, Chen Fei paused and looked around. Zhao Jiayu quickly took out the paper and pen from his bag and handed it to Chen Fei. Chen Fei drew a sketch, then pointed to the sketch and said:

"Old Huang, look, this diagram shows a general detection block diagram of distance expansion target, mainly including two parts: the formation of adaptive thresholds and the formation of detection statistics.

These two parts face the following difficulties under high-distance resolution conditions: (      1) How to accurately estimate the increased target parameters; (    2) How to control false alarms in non-Gaussian environments; (     3) How to adapt to the complex motion mode of the extended target; (     4) How to improve adaptability to the actual environment and robustness to mismatch situations; (    5) Study efficient algorithms with low computational complexity.”

Huang Lihua just listened carefully at first, but soon, his eyes lit up, getting brighter and brighter. Finally, he slapped the table with a slap and shouted excitedly: "Wonderful!"

Zhao Chenggong didn't understand radar very much, but he understood Huang Lihua. Seeing that guy was so excited, he couldn't help but look at Chen Fei in surprise.

Huang Lihua's vision is so high that she is even more famous than him. But now, this guy is so excited that he can't help himself. It's not easy.

Before coming here, he was full of expectations for Chen Fei's prop gun. He felt that it was not just a prop gun. As long as it was polished and polished, it could be turned into a real gun.

The Ordnance Group is planning to build a sturtle-free rifle specifically for export, so he gave it the design plan for this sturtle-free rifle.

He had already had some ideas about his own, but after looking at Chen Fei's prop gun, he felt: Damn, what's the thing I made!

So he came to find Chen Fei today.

He was already full of expectations.

Now after seeing Huang Lihua's reaction, his heartbeat suddenly thumped.

Today I'm going to have a great fortune.

He thought excitedly.
Chapter completed!
