Chapter 1646: I want revenge! (under)

Just like Tan Zhenhua told Xie Li, the signal on the meter wave radar screen is so weak that it is almost ignored by the system's automatic filtering. Its flight trajectory has obvious regularity. Although the speed has not exceeded the speed of sound, it is not a Bluestar. Xie Li can now be 100% sure that the creatures on the planet can continue to achieve it. That is a metric stealth fighter!
Because after the war began, the sky over Serbia and Montenegro has been unilaterally declared as a no-fly zone by NATO. No more civil aviation or private planes dared to pass in this airspace. Moreover, as the warplane of Velikovic was shot down, There will never be any fighter belonging to Serbia and Montenegro in the sky.
Even the process of identifying friend or foe can be skipped. All man-made flying objects are enemies!
The accuracy of the meter wave radar is limited, and it can only indicate the approximate position of the aircraft, but at least it can keep track of it not continuously.
that's enough.
Tan Zhenhua told him that the so-called stealth fighter is actually not completely impossible to detect. It is just that it has made the radar reflection area as small as possible, which has greatly shortened the detection range of the radar, and it is based on the current human knowledge. With the technical capabilities, fighters that are optimized for stealth in all radar wave frequency bands are still in the category of science fiction. The most important stealth fighters currently in service are optimized for the X-band of the fire control radar. Other frequency bands can only be taken into account as much as possible. Therefore, even if some long-wave radars can detect this type of aircraft, it is difficult for air defense weapons to target them, let alone attack them.
But Tan Zhenhua also told him that stealth fighters are not without flaws. For example, its biggest flaw is that in order to achieve radar stealth during flight, the weapon systems of this type of aircraft are all built into the magazine. When it wants to launch an attack, it must first open the built-in magazine, and at this time, it will inevitably destroy its precision-designed radar stealth shape. When its radar reflection area is the largest, of course, the fire control radar locks it. The best time!
Of course Tan Zhenhua also told him that in today’s world, apart from the United States, there is no second country equipped with a stealth fighter. Therefore, all these conclusions are based on theoretical inferences and have not been obtained. After valid inspection and certification, he can't guarantee what the actual situation will be.
Well, in fact, Tan Zhenhua knows the correctness of this theory, because he was reborn from another time and space in 2017, and in that time and space in 2017, China has successfully developed the "J-20" fighter, becoming the only second in the world. For countries that have developed and equipped such advanced fighters on their own, do you think that the 4014 Institute, which is the leader of China's national radar industry, has not done relevant experiments?
No one believes that, right?
What classmate do you say is not the only one, and Maozi’s "Su 57"?
Well, just the slapped "flank guard", Qian Zhiyu can say responsibly that the reflection of radar signals is as strong as the fly on top of a bald head...
As for Xie Li, since Tan Zhenhua said this, then Thaksin, and he must use actual combat to prove it!
On the meter wave radar monitoring screen, the weak signal was flying along the predetermined route violently, without even realizing that its traces had been exposed. Perhaps the pilots on the plane were full of powerful technologies for the United States. And self-confidence of strength, and contempt for opponents?
"Preheat the fire control radar." Xie Li gave the first order.
Stealth fighters, because of their extremely low radar reflection cross-section, have very good low reflection properties for radar waves, especially the X-band where fire control radars usually work, but the low reflection is also reflection, and when radar is used for this property Corresponding improvement measures have been developed, such as focusing on multiple beams of radar waves to scan specific areas in a targeted manner, implementing the so-called "gaze" mode; for example, improving the sensitivity of the filter circuit; for example, improving the circuit to reduce system noise interference; Improve the signal processing algorithm and do special processing for some special signals...
In this way, when conducting a directional search for a specific area, the so-called "stealth fighter" will always reveal the fox's tail.
Just like now, this moment.
At a distance of 65 kilometers, it has entered the attack range of the "Red Flag 17" system. On the meter wave radar screen, the weak reflected signal suddenly became strong. This is a signal that the fighter is preparing to attack, and it opened the magazine!
It's now!
"The fire control radar is on!"
Although the electronic level of Maozi has always been called the "big coffee table" in contempt by Tan Zhenhua, the 64N6E three-coordinate radar system is, after all, a passive phased array radar that is one generation ahead of the traditional radar. In the process of localizing it, Huaxia has optimized and replaced a large number of advanced electronic devices, and has completely upgraded the signal processing unit of the radar. Compared with its prototype, this radar has already achieved considerable performance. Progress, the system noise has been greatly reduced, the sensitivity has been greatly improved, and many new functions have been added. At the same time, the reaction time of the whole system has been greatly shortened. Therefore, under the condition of sufficient preheating, it only takes less than 7 seconds. The C3I system has already given a hint-the fire control radar locks the target!
Xie Li promptly issued an order: "Dongyao, Dong3, Dong5, Dongguai, prepare to attack!"
Lei Tao responded in a sonorous tone: "The order is received, Dongyao, Dong3, Dong5, Dongguai, preparations for attack...Ready to complete!"
Xie Li's command did not stop:
"hit!"
Without hesitation, Lei Tao pressed down the 4 launch buttons in a row.
Four 48N6E missiles were ejected from the launch tube by high-pressure gas at almost the same time, and then the main engine was ignited in mid-air. After a large arc was drawn, a huge tail flame was sprayed, and a beautiful trail was dragged in the air. Line, galloping towards the distance.
In the shelter, everyone's eyes are fixed on the radar screen representing the missile's several light spots, because they know that at this moment, they are making history-this is the first time since the birth of the US stealth fighter. Once on the real battlefield, someone actively and consciously launched an attack on it!
The measured single-shot hit rate of the "Hongqi 17" system is roughly similar to the theoretical data of the prototype S300 system, between 80% and 90%. Under normal circumstances, a double-shot salvo against a single target is already a saturation attack, but Today, with the limited inventory of missiles and the possibility that no supplies will be available in the future, Xie Li still issued a four-round salvo order, which shows his determination.
Definitely, we must knock it down!
For some reason, at this moment, what flashed in Xie Li's mind was the cold light that flashed in his eyes when Tan Zhenhua specially called him to Xiangjiang and repeatedly asked various precautions.
This is something he and Tan Zhenhua have known each other for so many years and have never seen it before.
The cold light was so bitter, Xie Li could feel the bitter hatred contained in it, as if it were as high as a mountain and as deep as the sea. Even if he was born and died on the battlefield for many years, he could not help but rise from the bottom of his heart. Shares chill.
He will never forget. When he asked Tan Zhenhua about his motive for doing so, the faint and gentle partner uttered four words from the crown of his clenched teeth:
That tone, the voice is like weeping blood, cold as ice!
"I want revenge!"
