When talking about this, Wu Shengli also felt a little funny. In the past, every time the Navy held an equipment meeting, they would definitely discuss the four-sided phased array radar, because this is what the Navy needs most.

What now? After talking for a long time, the four-sided phased array radar took the least time. Why is this?

Of course, it is because the strength of the navy has increased and the technology of the military industry is leaping forward! When the 052c was launched, it has become the first ship in China and the first ship in the world. The American Aegis still uses passive phased arrays, and our own side can already use it.

Active phased array radar!

Now, the radar has been improved from 346 to 346a, which has stronger performance. However, in the eyes of the top brass of the Navy, this is already a matter of course. Therefore, there is no need to continue to struggle with this project. As long as the 14th Institute continues to engage in research and development, this

Will suffice.

The Navy is concerned about other things instead.

For example, intercepting ultra-low-altitude sea-skimming missiles, such as intercepting ballistic missiles.

Now, let’s get back to the topic.

"The radar has almost been said. On the mast at the back, we installed a meter-wave radar. In addition to providing long-range early warning capabilities in peacetime, it also has the ability to detect stealth aircraft. In our 052c and J-32

This has been confirmed during cooperative training." Qin Tao said: "However, our 517b is still too backward, so our 14th institute has come up with a brand new product."

Xing Wenge was only in charge of the 346 radar. After talking about this radar, he came down and Mr. Ben came up.

"Dear leaders, let me now report to you the newly developed radar. This is a new radar built by our 14th institute using the most advanced technology. It is not only used in naval equipment, but also in ground radars.

, continue to weave an airtight radar network for the airspace of our motherland."

"Lao Ben, looking at the way your 14th Institute looks like, it seems that you pay more attention to it than the 346a radar?" a naval leader said.

Mr. Ben boldly delegated power and asked Xing Wenge to develop the 346 radar. However, Mr. Ben was actually responsible for this seemingly backward meter-wave radar.

"Our 14th Institute was originally engaged in ground-based long-range radar." Mr. Ben said: "I am also using my remaining energy. This radar is my last project before retirement, and I must do it well."

"Okay, Lao Ben, let me introduce you. Wait, why does your radar look like a flat panel? It's just like a large fly swatter." Looking at the pattern that appeared on the projection screen, a navy man

The leader spoke.

Although Qin Tao had already given the design of the entire warship at the beginning of the meeting, it was just a quick glance after all. The big guy didn't pay much attention to the big guy poking at the rear mast. Only now can he finally see it clearly.

.

The previous 517b radar was a Yagi antenna, which was a rotating rod with some vertical rods placed on it. Although it was three-dimensional, it was still inherited from the ancient Yagi antenna. Now? It has become a flat plate.

!

"Yes, this is a good name. From now on we will call it a fly swatter." Qin Tao interjected: "We finally upgraded from a clothes drying rack to a fly swatter. We will be able to better detect flies in the future."

"On the 517b radar, we use the p-band, which has a long detection range and low power, making it easy to turn on for a long time. Now, our brand-new meter-wave radar also uses the normal band when working as a long-range early warning radar.

to use.”

"We usually work on the normal band, but during the war, can we change to another band?"

This is very important! You must know that during war, radar is the first target that the enemy must destroy. The enemy's anti-radiation missiles will attack the radar station as soon as the war begins. As for the parameters of these radars, they are collected in peacetime.

Yes, after all, as long as the radar is working, it will radiate electromagnetic waves, thereby leaking its own signal characteristics.

(Can anti-radiation missiles kill meter-wave radars? The Hero of East China really doesn’t know. It seems that this kind of anti-radiation seeker must be at least half a wavelength long to receive radar waves? Some information says that our fly swatter

The two-dimensional working mode of the active 3D system is used. The East China Hero did not graduate from elementary school and cannot understand this sentence.)

"Yes, once wartime comes, we can still switch within the meter wave band at any time."

P band is a meter wave band. Because it was used in the past, it is commonly called p band. P means past. The frequency of this band is between 230 and 1000 MHz. Therefore, it is not fixed on a specific band.

It's completely switchable.

"Have you developed a brand new radar magnetron?" Wu Shengli said.

Before the active phased array radar, all radar wave emission required a radar magnetron. This is a special electronic tube specially used to radiate electromagnetic waves. In this regard, China is still very powerful.

Although we have transitioned to the era of active phased array radar in recent years, we have not given up on the research and development of this kind of electronic tubes. We are still developing new products. After all, this can not only be used in radars, but also in microwave ovens.

"Yes, we have newly developed the radar magnetron. At the same time, we have used brand-new electronic technology to transform it so that it has more advanced performance and can fully undertake the tasks of warning and anti-stealth."

"This radar is good, what's its name?" Wu Shengli asked.

"On the land-based radar, we call it jy27 radar. On the navy side, we haven't named it yet," Mr. Ben said.

Different radars have different numbers. Although these domestic numbers look like English letters, they are actually Chinese pinyin. j stands for maneuver and y stands for early warning. They are the first letters of the Chinese pinyin of these two words. If the navy's radar

It would be inappropriate to continue using this name. After all, the navy does not need to be mobile.

"Our navy should get a new number. Mr. Qin, what do you think?"

Upon hearing the leader's question, Qin Tao said without hesitation: "How about calling it 517c?"

The 517 radar is an early warning radar commonly used by the Navy. It was later upgraded and became the 517a. Later, when the 052c was put into service, the 517b was improved. Now, it is the turn of the 517c.

"Mr. Qin, our radar has no inheritance from the 517 radar. It is newly developed." Mr. Ben said.

"Yes, that's why we call it 517c."

Wu Shengli nodded: "Yes, true or false, this is the best way to fool people. At present, our warships have placed meter-wave radars to detect stealth aircraft. The method has not been discovered by the outside world. Of course we can still
