The biggest financier, the richest person in the whole of China, Yang Yuanzhao, a chaebol of one person, said so, the probability of success is so high, how can it not be carried out, but a radar prototype, the cost is really expensive, just the production of a core machine, it is as high as 5 million, plus ancillary equipment, at least 7 million, this does not calculate the labor cost, according to the current minimum of 500 people to serve the space-based radar project, 37 professors and above, 105 ordinary lecturers, and about 400 master's students, doctoral students, The artificiality of these people is also a relatively terrible number.

The first radar is really a failure, not the failure of the whole machine, but only the failure of some systems and units, after careful research, after finding out the problem, with the support of Yang Yuanzhao, a new round of trial production began, similar failures after 7 rounds, but in the end did not completely overturn the overall architecture, after perfecting many details and sub-units, the whole project went quite smoothly, and finally a completely different from the current mainstream radar in China, a lot of lighter radar appeared.

Even if there were some twists and turns in the middle, but in the end, this prototype still appeared, it didn't look beautiful, and it didn't even have a shell, but it made the entire space-based laboratory shout excitedly, I don't know how much hard work it went through, I don't know how many sleepless nights it went through, but the final thing was made, and when it was turned on and running, on the display screen of the radar, showing the unique curve of the radar, everyone cheered.

This radar, which is temporarily named Doppler type 1, is different from the previous radar, the overall use of a large number of new materials, the specific gravity above, lighter than the previous radar, after the design of Doppler and single pulse, there is no need for sea-based radar, with a high mast as an antenna, as long as a reasonable arrangement, the antenna is buried on the aircraft fuselage, the reception and transmission ability is much weaker than that of the sea-based, but the weight has dropped a lot, the volume has also decreased, saving at least two-thirds of the area, It has brought a massive reduction in size and weight, which is a significant step forward from the previous space-based radar.

Taking into account the factors in the air, it is not necessary to build a huge antenna to prevent leaks and dead angles as on the ground, and to a certain extent, the entire fuselage of the aircraft is an antenna, which is amplified by acceptance and finally transmitted to the radar for processing. This design is very genius, in terms of reducing a certain accuracy, even the measurement range of the radar has been reduced, from a maximum of 400 kilometers in the sea base, to 85 kilometers, and when the final physical product is made, it is much less than before, with a total weight of 17 tons and a volume of about 30 cubic meters.

This volume has not yet reached the final use volume, but it is a big step forward from before, in a sense, this is a radar that can be put on an airplane, and if the heavy bomber is completely modified, so that all his volume is used to store radar, it is enough to load this radar into it, and it is enough to use it for experiments.

The emergence of this prototype represents that the development of radar has entered a correct channel, compared with the previous weight of hundreds of tons, or even hundreds of tons, 20 tons of weight, the possibility of weight reduction is suddenly much greater, the most important thing is that when the prototype appears, and it can be installed on the aircraft, many air theories are speculated before, at most get a height of tens of meters for experiments, the radar is too big, it is not good to go to a mountain hundreds of meters high, or to get on a tower.

Then, the most critical issue in the development of airborne radar, air performance, has become the most critical issue, but there is a problem in front of everyone, that is, a strategic bomber, must be modified before such a radar can be installed, then a heavy bomber must be paid, even if the radar test is successful, the future of this aircraft will not go through large-scale modification, it is equivalent to scrapping.

A heavy strategic bomber, his cost is 800,000, cheaper than radar, but similar experiments, not all at once, I can't say how many more, money is not a problem, radar laboratory, there is enough money, but he can't affect the Air Force for the time being, strategic bombers in the first day of appearance, it showed strong strength, this as the ultimate pole of the Air Force, but also the most extreme strike force, has always been controlled in the Air Force General Headquarters, others, there is no way to use this.

In the end, it was Yang Yuanzhao who solved the problem, and with a wave of his hand, 10 strategic bombers that had not yet been off the production line were sent to the radar research institute, to be exact, on the aircraft production line, the researchers of the radar research institute would inform the aircraft manufacturer of the radar data and precautions, and then the vigorous modification began.

Of course, at present, there is only one prototype of the radar, and it is necessary to carry out a certain production according to this, and then it can be installed on the aircraft, and then it is the experiment of the plane flying into the sky and the theoretical experiment on the ground At the same time, this is also the most important work of the radar laboratory during this time.

Although Yang Yuanzhao has a huge role in promoting the radar project, he only understands the theory, and even said that he has only heard a few terms, a lot of more in-depth things, and needs more researchers, in-depth understanding, to use, which requires experiments, wasting 10 strategic bombers, such aircraft, China has thousands, relative to the benefits of radar, what is the point of payment, as long as the airborne radar project is finally completed, the radar will be China's aircraft carrier battle group, support a piece of the sky.

The radar was installed on the plane, this is the first time in the world, even a senior researcher does not dare to guarantee that all the indicators of the radar on the aircraft can be determined, and this radar is still a prototype, itself has a series of problems.

This one is only equipped with radar, nothing else is equipped, even if it is self-defense firepower, most of the aircraft are dismantled, some are similar to the early warning aircraft of later generations, but the simple radar early warning aircraft, for this era, there is not much effect, the aircraft of this era, the battle is combat, the two sides are fighting in a certain area, the longer range of radar detection, at most just to guard against sudden sneak attacks, you can't always fly them to the sky all day long in order to detect sneak attacks, only a thousand days to be a thief, no thousand days to prevent thieves.

The first time I flew into the sky, there was a problem with the radar, the plane got some batteries, but it was not enough to turn on the full power, after the full start-up, the radar directly blacked out, turned off at least 7 auxiliary equipment, and adjusted the power of the radar to the minimum, this was barely turned on, the first experiment was only in the air for 30 minutes, and then hurriedly landed, at most with the radar on the sky to go around.

However, this time in the sky, has accumulated considerable experience, all kinds of data transmitted back, for the advancement of radar research is quite large, take it for granted that the radar to the sky, and the real sky, these are two different things, in the sky, there are two different up and down, focusing on one aspect, it will inevitably weaken the other aspect, before the comprehensive strengthening is wrong, after a slight change, the radar removed at least 2 unimportant units, weight reduction of 5%.

This is not a small number, 5% of 20 tons, about a ton, it can be said that it is more than the previous largest weight reduction, from this point on, as if to open the mind, everyone is crazy thinking, how to pull the next piece on the radar, weight reduction on the one hand is functional, more important is the use of newer materials, more unique design, has achieved the result of using lighter weight to ensure the quality of radar.

China's effect on new materials is amazing, plus, the measurement range of the radar, can not be used too far, ordinary radar, the measurement range may be more than 300 kilometers, the air radar can not be so much, 300 kilometers is a waste for him, and even from the experimental data shows that the same performance of the radar, at high altitude and the ground measurement range is not the same, the higher the altitude, the more the measurement range, 500 meters at an altitude, than on the ground, at least to improve a considerable degree, This was also the fundamental reason why radar stations were mostly built in the mountains and had a huge antenna.

No matter how high the mountain peak is, it can not be higher than the plane, the plane will always fly higher than the mountain peak, according to the current Chinese aircraft in the 8000-10,000 meters ceiling, Mount Everest as the world's highest mountain, but also more than 8400 meters, the plane can easily fly over him, and the current limit of the Chinese aircraft can reach more than 15,000 meters, this height is the peak can not reach.

Besides, more than 4000 meters of mountain peaks, radar is not easy to get, dozens of tons, dozens of cubic meters of big guys, not so easy to get, after the first discovery of the radar ranging distance, and then specially designed the radar ranging law, when the height reached 4000-10,000 meters, this improvement is quite outstanding, which has also become the basic judgment of the future radar height.

It is precisely because of the height that the detection range of the radar has increased, and from the perspective of actual combat, the radar does not need much detection range, within 100 kilometers, which is almost equivalent to dozens of kilometers on the ground, which to a certain extent, promotes the miniaturization of the radar, it is not easy from small to large, but from large to small, as long as it does not enter the microscopic world, under the premise that the prototype has appeared, it is much easier.

From about 250 kilometers, reduced to tens of kilometers, 5 times faster reduction, the weight of the radar of course can not be reduced by 5 times, but the overall reduction of the radar is quite obvious, reducing the weight by almost 4 percent, compared with before, the weight of the radar has finally been reduced to less than 11 tons, which is basically up to expectations, and can be installed on strategic bombers.
