Chapter 1426: Anti-missile operations (part 1)

Now, you can only fight for your character!
I hope that after these months of training, the soldiers have mastered the performance and use of the equipment. I hope that the weapons and radars that have been spent heavily are useful. I hope that God, Queen Mother, Tathagata like Buddha, and God are all today. Go to work and stand on your side!
Tan Zhenhua could not explain, he grabbed Jiang Zhimin and sat down on the command system. He flipped a few buttons on the console to switch the call to broadcast mode. He picked up the microphone and drank: "Attention, All the personnel of the base should pay attention to the missile attack, the air defense company is preparing for battle, and the rest are hidden. This is not an exercise. Repeat, this is not an exercise!"
At the same time, Tan Zhenhua suddenly felt a generous palm pressed against his shoulder. When he looked back, he saw Xie Li nodding at him.
He understands what Xie Li meant. At this time, Xie Li unconditionally handed over the command to him, which meant trust!
60 seconds left!
Tan Zhenhua couldn’t care about whether the base would be in chaos after he issued that order. At this time, he could only hope that the first reaction and battlefield instincts of these war-tested soldiers would be the next step. The second order was issued: "Air Defense Company report the situation!"
A few seconds later, a familiar voice came from the speaker. It was Lei Tao, commander of the air defense company: "The air defense company’s combat status, equipment inspection, ammunition inspection, and fire control radar power on to warm up."
Finally came the first good news.
It seems that the previous stage of training has achieved the effect. While the air defense alarm sounded, the instinct of these fighters in charge of air defense was to switch from combat readiness duty to combat state immediately, turning on the fire control radar and inspecting equipment. This shows that they have begun to adapt to new tasks and combat methods!
It should be noted here that, as a high-precision radar working in a high frequency band, fire control radar itself consumes considerable power, and the service life of some core components is also extremely limited. For example, the core of the radar is also a radar. One of the most expensive components on the high-power grid-controlled traveling wave tube, its average failure time is theoretically only 500 hours, which is theoretical, and may be shorter in actual use, so the fire control radar is usually not turned on. Of course, it In fact, there is no need to turn on 24 hours a day.
Because the wavelength of fire control radar generally works in the X-band of the centimeter wave, the detection accuracy will be relatively high but the distance will be relatively close due to the influence of the wavelength, and it is difficult to achieve a large-scale airspace search. Its job is After calibrating the airspace of the target, it accurately locates it and guides its own weapon system to attack it.
The task of full-airspace alert search is usually handed over to air-crew alert radars. Longer wavelengths, such as meter waves or decimeter waves, are used. In this way, a longer search distance and a larger range can be obtained with a smaller transmission power Search range, and the service life of this type of radar is relatively long. Many models can even be turned on for 24 hours. For example, the type 517 "drying rack" radar for battleships mentioned above, and Tan Zhenhua’s "synthetic" radar. Among the equipment designed by the battalion’s air defense force, the latest development of the 4038 Army’s air defense accompanying three-coordinate warning radar JY-9 was used to carry out this task.
The designer in charge of developing this type of radar is the former colleague of Tan Zhenhua’s father, Tan Ming, and Xue Zi’s father, Xue Guowei’s most proud subordinate. Later, Wang Xiaosha, who went to 4038 to support the third-line construction, was also the first type of China to invest. Actual combat three-coordinate warning radar.
It is said that when Tan Zhenhua broke the "view of the door" when he bought this radar from 4038, he was still criticized by the lame, "How can the fat water flow into the field of outsiders" or something, but at that time, the time was tight, and the set of 4038 The radar has been successfully developed. It can be regarded as a shelf product. You can get it when you buy it, and it can be used as soon as it arrives. This is why Tan Er chose it in the end.
JY-9 is a radar with excellent performance, but limited by its own system and working wavelength, it can only be used to find targets and mark positions, but cannot accurately guide weapons to attack targets. Therefore, the combat process of the air defense company is: JY-9 is on duty for daily vigilance and combat readiness. After the target is found and calibrated, the target airspace and target flight trajectory are calculated and transmitted to the AF702 fire control radar. Then AF702 will track and lock the target and guide the weapon to launch an attack.
The AF702 radar is actually the land-based version of the PD radar installed in the "Flying Leopard" fighter. Some improvements have been made to adapt to the land combat environment. At the same time, some functions that are useless for land warfare have been cut off, such as synthetic aperture and terrain. Surveying and mapping, etc., while reducing the difficulty and cost of development, it also greatly shortens the development time, so it is so fast. This is what Tan Zhenhua has always emphasized in the "cheats" provided to 4014 by Tan Zhenhua. Modularization can facilitate the timely introduction of applicable models based on actual needs, and can also greatly reduce the workload of battlefield logistics.
Because it is improved on a mature model, the performance of the AF702 radar is very stable, but it also has inherent shortcomings-it takes at least 10 seconds to warm up to the working state of the PD radar using the traveling wave tube...
There are still 30 seconds!
"The fire control radar found the target!" Lei Tao's voice finally came from the microphone.
This is the second good news!
"The equipment inspection is complete, the ammunition inspection is complete, and it's normal."
Lei Tao's voice was steady and strong, as if the incoming missile did not cause any mood swings in him.
A 20-second countdown clock suddenly popped up on the screen in front of him. Tan Zhenhua knew that this meant that the fire control radar successfully tracked the target and calculated its trajectory.
For a large target such as "Sud", the longest tracking distance of the AF702 radar reached 30 kilometers. This is because its power configuration and everything are followed by the original design in order to save trouble. According to the equipment on this set of "Lu Shield 90" The weapon system actually belongs to the "exceeding standard" configuration, because the farthest weapon on this system is the "Mianwei 1" infrared ground-seeking missile with a range of 5 kilometers. Even if it is locked, it can only wait for the target to enter. This attack range can be hit, but in fact? The "Qianwei 1", the first generation of infrared-guided individual missiles, cannot deal with the "Scud" missiles that strike at 3 times the speed of sound. The only thing that can be hoped for is the Chinese version of "Oerlikon" with a maximum range of 4 kilometers.
A simple calculation will tell you that with a "Sud" attack speed, it only takes 3.33 seconds for a distance of 4 kilometers. In such a short time, it is impossible to organize a second interception. In other words, if the first interception fails. , Basically the ending of GG!
The numbers on the countdown clock were beating quickly, but everyone in the command cabin felt that every second was so long.
