Unconsciously, the era of phased array radar has been entered.

Ordinary radar, the antenna is rotating, radiating to different directions, the flat slit radar antenna is the same, it also needs to rotate, but the phased array radar is not, the antenna of this radar will not rotate, it depends on directly changing the phase of the radar wave, directly changing the direction.

Phased array radar is not special, in the past few decades, many long-range early warning radars on the ground are phased array system, but to make it small, put on the aircraft, it is not easy, it has adopted a new generation of active phased array radar, the entire radar antenna plane, divided into a small component, each called T/R, this is actually a tiny integrated circuit, so, especially test the processing capacity of the electronics industry, at present the world can be made, no more than a slap.

The MiG-31 is also a phased array radar, but it is a passive phased array, which is carried out by a ferrite phase shifter, and cannot be compared with an active phased array radar.

Because it does not need to rotate, it can be distributed in a plane on the plane, and this system was pioneered by the Israelis.

Of course, they are actually in the R&D stage and have not yet achieved results, but R&D also needs funds, so after releasing this signal to the outside world, China has responded positively.

After all, when I used to introduce projects such as the Monster Snake 3 missile, it was quite pleasant to cooperate with them.

The development of an AWACS aircraft takes a long time, and even longer if it is international cooperation. So, this project, in fact, began in 1992, at that time, the project in Israel had already begun, when after the launch of this model, the country responded positively, and after four years of negotiations, finally in 1996, the two sides reached an agreement.

This is China's Filcon early warning aircraft system, choosing Russia's Il-76 early warning aircraft as a platform, installing Israel's own research and development of the Ferkang system, each system is priced at 250 million US dollars, and the first early warning aircraft will be delivered within four years.

Now, more than two years have passed, and this agreement at that time has also attracted more and more people's attention, after all, Israel's early warning aircraft system, the performance is also very powerful, for China, there is already an advanced Su-27 fighter, if there is this kind of early warning aircraft, the level of modern equipment of the Chinese Air Force, there will also be a qualitative leap.

Now, hearing what his sister said, Qin Feng suddenly became excited, this kind of thing, he didn't even know it, in the past few years, he has pounced on Jianten!

"Can this system be integrated into our data chain?" Qin Feng said.

Speaking of early warning aircraft, many people will say how far the search distance of the early warning aircraft, how many targets are tracked at the same time, etc., in fact, for the early warning aircraft, in addition to the quality of its own radar, there is a more important one, that is, the support of the data link!

If there is a data link, the data of the early warning aircraft can be directly sent to the fighters, so that the fighters' operations are more efficient, and the early warning information can be received at any time, which is very important in the ever-changing air combat.

This is also the reason why the country did not buy the An-50 early warning aircraft, this early warning aircraft developed in the Soviet era, is comparable to the E-3 early warning aircraft, but, compared with the E-3 command ability of hundreds at every turn, this An-50 early warning aircraft can only command more than a dozen fighters at the same time, so that the role of the air command of the early warning aircraft is greatly reduced, the reason is that the Soviet early warning aircraft has no data link, can only voice guidance, a guide, at most two fighters to guide the operation, only data link, Only then can we make a radical change in our command ability.

Since this kind of aircraft is developed for its own side, of course, it must be used in its own system, and the Jian-10 fighter fights under the command of this kind of early warning aircraft, just thinking about it is enough to make people feel satisfied, and this is modern warfare.

Qin Feng was full of interest.

"Well, I don't know." Qin Xue said: "I'm not from this project. ”

Although it was developed by Israel, in the process of research and development, many domestic engineers also passed, and 14 institutes were the units that developed the airborne pulse Doppler radar, and of course the largest team was dispatched.

However, Qin Xue didn't go, Qin Xue's face was full of regret, however, she touched her stomach and said: "After our current airborne radar project is over, I will prepare to give birth to a baby, and the early warning aircraft project is estimated to be several years, so I didn't take the initiative to ask for help." ”

Qin Xue didn't know that she should give birth to a baby, she couldn't delay it any longer, since college, she has pounced on the 1471 radar, and until now, when the radar is finalized and equipped with fighters, she can retire.

The early warning aircraft project, that is the Tianzi No. 1 project of the Air Force, after studying the radar for so many years, she did not participate in the early warning aircraft project, of course, there are some regrets.

"Let's go, let's eat." Qin Feng pulled his sister and looked at his brother-in-law who was packing up his things on the other side: "Let's go, I'll treat you to something delicious!" ”

After coming to Chengdu, my sister's face gradually became rosy, which is inseparable from Qin Feng, the thin sister, malnutrition, Qin Feng looked distressed, so he took her to eat more delicious food, my sister has been too busy over the years, and now, the installation of the on-board equipment of the No. 3 machine is also in a hurry, and the assembly progress of the whole machine is determined, so take my sister to eat more, take care of the body, and give birth to a healthy baby in the future.

After eating at noon, in the afternoon, I entered the workshop again, the No. 3 prototype was in full swing production, Qin Feng entered with him, and he could see the part of the machine head, which was also being installed in an orderly manner.

"We have adopted the Western design concept, in the form of a plug-in board, once there is a fault, the circuit board can be directly unplugged and repaired." Qin Xue looked at the reserved space in the nose of the machine, and began to think about the installation.

Not only because of the circuit of the plug-in board, but also because of the 1553B data bus, this technology can be said to be a technological revolution on the fighter, making the data transmission of the fighter more efficient, and also allowing various devices to communicate directly.

Although the original peace model project failed, China still learned a lot of experience, and this 1553B data bus is one of them.

Qin Xue, who was wearing work clothes, threw herself into work again, and I have to say that her sister also has a unique feminine charm at work, showing the heroic appearance of scientific research workers.
