Military Industry of Great Powers: Build the Strongest Flanker

As Tong Yihong's finger pressed the search button, the CRT screen was suddenly covered with snowflakes. This was clutter on the ground. After two or three seconds, the program to remove the interference from ground clutter was started, and the continuous interference radar waves from stationary targets on the ground were started. After removing it, the screen suddenly became much cleaner, leaving only seven conspicuous bright spots.

There is also a series of numbers below each two dots.

"Target No. 1, with a left deflection angle of 23 degrees, a height of 112 meters, and a straight-line distance of 3215 meters!"

"Target No. 2, with a right deflection angle of 32 degrees, a height of 75 meters, and a straight-line distance of 4532 meters!"

"Target No. 3, with a right deflection angle of 42 degrees, a height of 213 meters, and a straight-line distance of 6585 meters..."

"Target No. 4..."

…

Zhao Guoqing frowned slightly, turned around and asked Ji Hongbo, "I remember that I applied for eight test balloons. Why does it show that there are only seven?"

Tong Yihong said: "General Master Zhao, do you want to interrupt the test and check the fault?"

"Continue testing for now!" Zhao Guoqing shook his head and said to Jia Pengfei behind him: "Pengfei, go to the telecommunications team and ask if the eight balloon stations are arranged normally?"

"good!"

As soon as Jia Pengfei left, there was noise from the crowd at the door. Zhao Guoqing turned around and shook his head helplessly.

President Mu and Director Liu Qing of the General Staff are here. To these leaders, the confidentiality work in this base is like a sieve.

"What's wrong, General Manager Zhao, you don't dare to notify us of the final assembly test? Isn't it because you are afraid that the chain will fall off on site?"

Zhao Guoqing stood at attention and saluted.

"Mr. Mu and Director Liu, you are welcome to come to the base to inspect the work!"

Tong Yihong didn't know if he should take the next step and waited for Zhao Guoqing's instructions.

Mr. Mu waved his hand and said, "You should do whatever you need to do and leave us alone!"

Zhao Guoqing nodded and said, "Why don't you wait a moment!"

Mr. Mu looked at Zhao Guoqing and asked, "What's wrong?"

"There's a little trouble, eight balloons, only seven in sight!"

Ji Hongbo closed his eyes, "Young man, you still have less experience. How can you say this kind of thing? Isn't it good to do the next test first, and then find the reason after completing the test?" You can’t cause trouble for the leader!

But Teacher Xiao Zhao had already said it, but he couldn't take it back. Sure enough, Mr. Mu's face became serious, and Director Liu Qing also stopped smiling.

This is not because the leaders are dissatisfied, but because they are also paying attention to this issue.

We must understand why only seven of the eight targets were found. If on the battlefield, an enemy plane leaked in, the consequences would be very serious!

Mr. Mu walked closer and took a look at the radar. He saw the difference of the phased array radar at a glance and asked quickly: "Why is this display different from other radars? Doesn't the radar antenna need to be rotated?"

Zhao Guoqing explained: "Mr. Mu, the transmission mechanism of phased array radar is somewhat different from that of Doppler radar. It relies on the radar beam to scan in a short time and adjusts the beam direction by moving the phase..."

"..." Mu Hu was a little confused after hearing this, and turned to Director Liu Qing and said, "It seems that I still need to learn. I have been dealing with radar for half my life, and now I can't understand it anymore!"

While speaking, a report broke the conversation.

When Zhao Guoqing saw the wrinkles on Jia Pengfei's face, he knew that it should be similar to what he imagined.

"Report, it has just been determined that the No. 6 balloon did not lift off normally!"

Zhao Guoqing nodded and said to Mr. Mu: "Mr. Mu, the No. 6 balloon has not lifted off. At present, all seven balloons have been detected. The phased array radar is working normally. Please let me know if you want to proceed with the next test!"

"Keep testing!"

"yes!"

"Keep testing!"

Tong Yihong shouted: "The next step is to lock the target test. Please call the balloons at positions 1, 3, 4, 5, and 7 to start moving!"

"yes!"

There are nine number keys from zero to eight on the phased array radar operation panel. Tong Yihong pressed the five number keys 1, 3, 4, 5, and 7 one after another, which represented the seven targets on the radar screen. The corresponding numbers above The five targets were immediately displayed with red rings, and the radar also made a beeping sound.

Zhao Guoqing explained: "When the target is determined to be locked, the computer will automatically strengthen the radar beam scanning of the locked target. Usually the scanning intensity is increased three times, and the intensity is increased five times under harsh conditions, but this will weaken the global scanning capability."

This was also criticized by Mr. Mu. It took two minutes to scan the airspace a hundred kilometers away.

"Balloon No. 1 has a speed of 20 kilometers per hour, a height of 126 meters, and a straight-line distance of 3,650 meters."

…

"Balloon No. 7, speed 35 kilometers per hour, height 212 meters, straight-line distance 23,580 meters!"

After Tong Yihong completed reporting the number, he turned around and said: "Report, the five tracking targets are normal and the radar is working normally!"

"call!"

There was continuous applause at the scene, and the sound became louder and louder. Director Liu Qing and Mr. Mu also applauded. At this point in the test, it can basically be declared a success. In the future, we will analyze the performance of each fixed-point test antenna. Data, analyze whether the signal strength of each beam meets the design requirements.

Mr. Mu said: "General Master Zhao, the balloon you just reported was 23 kilometers away. It can be detected, right?"

Zhao Guoqing nodded and said: "This is the ultimate distance for flat ground testing. The earth is round and X-waves cannot be reflected through the atmosphere. If the radar is placed on a tower or at a high altitude, it can detect a hundred kilometers!"

Liu Qing nodded and said, "Even the detection range of 23 kilometers is much better than what we had before. Thank you for your hard work, comrades!"

Success!

We succeeded!

Many people couldn't control their tears!

Zhao Guoqing was also infected by the warm atmosphere. Ji Hongbo, Liu Qing and others looked at Zhao Guoqing with unusual eyes.

It can be said that this project was completed by Chief Engineer Zhao on his own. The high-frequency current and high-low voltage conversion that troubled many radar engineers was easily solved by Chief Engineer Zhao.

Especially those involved in the research and development of chip software, they still can’t believe that they knew nothing about chips, and in half a year, they actually designed a phased array radar for fire control on their own hands. of chips.

How can this be!

This is real!

"General Master Zhao!"

"General Master Zhao!"

The whole audience was cheering, and the sound could almost lift the ceiling above their heads. The company responsible for security also sent people over to check, thinking that something had happened.

"General Master Zhao, General Master Zhao!"

Liu Qing nodded. At first, he was worried that Zhao Guoqing would not be able to support the position of chief designer. Now it seems that the young man in front of him can take the lead at any time.

General Muhu did not look away from Zhao Guoqing.

"The key is that you're still young, it's not easy!"

He immediately took off his belt, took off the gun bag, and handed it carefully to Zhao Guoqing's hand.

"Comrade Zhao Guoqing, I am willing to admit defeat. This gun is yours!"

"..."

"Mr. Mu, it's not considered a success yet!"

This is the preliminary test to see if the function can be realized. There will be a data link test later to interconnect the missile information and whether the fire control lock position is correct, not to mention moving the phased array radar onto the aircraft, which is also a big project. !

"If the actual test fails, I will get the gun back!"

"..."

You can still play like this! The key is that he doesn't play with guns. Putting them in his hands is like a hot potato, and he has to worry about whether they will be stolen!
