【Foreword】
According to a report by the South China Morning Post on April 18, 2024, Chinese scientists have developed a new radar technology capable of boosting the signal of stealth fighters by a factor of 60,000, while the U.S. military's F-22 fighter jets are like "naked running".
Is this really the case? How good is our new radar technology in China?
[Enhanced by 60,000 times!] The U.S. F-22 fighter is like a "naked run"]
In recent years, China has made remarkable progress in anti-stealth radar technology, which can track and detect United States stealth fighters, among which the JY-26 meter-wave anti-stealth phased array radar system developed has demonstrated its powerful detection capabilities, and this technology is also considered one of the world's top levels.
In addition, Chinese scientists have made a major breakthrough in radar technology, which is able to enhance the radar reflection signal of the F-22 by a factor of 60,000, making its equivalent radar cross-section (RCS) more than 6 square meters.
Developed by Xie Junwei's team, this technology not only significantly improves the ability to detect stealth fighters, but also covers a vast battlefield area, about 63,000 square kilometers.
By adjusting the beam parameters and power of each radar through a centralized networked radar system, the technology is able to accurately locate the F-22 in real time with an error of only about 20 meters.
This means that even at a distance of 200 km, the Chinese radar system can detect and pinpoint the F-22 fighters.
And the technology also covers an area of about 63,000 square kilometers, where the F-22's trajectory will be nowhere to hide, no matter what kind of maneuver it takes.
This new radar technology not only improves the ability to detect stealth fighters, but also significantly increases the probability of interception and reaction time, greatly enhancing the combat capability of the Chinese Air Force.
Hello gentlemen, the author's keyboard works overtime until the early hours of the morning every day, and he can only earn dozens of dollars a day, and it is not easy to write, so he added ads to unlock the text, just to make a little more money, the ads are only 5s, and you can read the full text for free after watching, I hope the audience will stop scolding.
At the same time, it also enables China to have greater strategic defense capabilities in the face of stealth fighters such as the United States F-22A, F-35 series and B-2.
Despite this technological breakthrough, there is still a gap between China and the United States in terms of overall air force strength.
Although China has a slight advantage in the number of heavy fighters, it is still qualitatively deficient, especially in the number of stealth fighters, and China lags far behind United States.
United States' F-22 and F-35 stealth fighters have a total of more than 487 aircraft, while China's J-20 has only about 100.
Therefore, in order to improve its overall combat capability, China is also constantly upgrading its fighter jets and actively developing new electronic warfare aircraft and other advanced weapon systems.
[How good is the stealth of the US F-22? ] 】
The U.S. F-22 fighter is known as the "Raptor", which is the world's first fifth-generation stealth fighter in service, which began to be developed in 1981 and officially put into use in 2005.
The F-22 is designed to surpass fourth-generation fighters and features a number of advanced technologies, including stealth performance, supersonic cruise capability, high maneuverability, and an integrated avionics system.
In addition, it is equipped with an APG-77 AESA radar, six LCD color cockpit displays, and an advanced communication/navigation and data link system.
These technologies allow the F-22 to play a significant advantage in aerial combat, achieving a "first shot, first kill" capability.
In order to maintain its leading position in the world, the United States Air Force has modernized the F-22 several times, especially in stealth performance, supersonic cruise capability, high maneuverability and integrated electronic warfare system, making the F-22 one of the most advanced fighters in the world.
The total radar reflection area of the F-22 is about 0.0001 square meters, which is smaller than the size of an insect, making it almost impossible to detect on radar.
In addition, the F-22 also adopts a variety of stealth design technologies, including a smooth overall shape, smooth lines, non-circular cross-section wings and high fuselage fusion, which greatly reduce the radar scattering area.
In addition to this, it uses absorbing materials and structures to further enhance stealth and is equipped with a thrust vectoring engine that is capable of providing additional maneuverability by changing the direction of the nozzle, making it more stealthy when performing complex maneuvers in the air.
The F-22's weapons bay is designed to be carried internally, rather than externally, which not only improves stealth performance, but also effectively protects the weapon from enemy fire.
Despite this, the F-22 still cannot escape the tracking of the mainland's new technology radar, which shows that the mainland's radar technology is indeed a cow!
【The development of China's radar】
After the founding of the People's Republic of China, the mainland began to take over the Kuomintang's radar research institute and gradually opened the foundation of the radar industry.
In the 1953-early 1960s, at this stage, China began to design and produce radars on its own, which marked the independence of the Chinese radar industry.
In 1953, China successfully developed the first self-designed 314A radar in New China, which was the starting point of China's radar.
Since then, China's radar industry has gone through the process of assembly and repair, imitation improvement and self-development.
In 1989, the airborne pulse Doppler (PD) radar developed by Ben De, an academician of the Chinese Academy of Engineering, broke the passive situation of mainland radar and realized "from scratch".
After entering the mid-70s, China's radar technology has entered a stage of development and improvement, and is widely used in military and civilian fields.
During this period, China's radar technology made breakthroughs in core material technology, especially active phased array radar technology, and made remarkable progress.
In the 21st century, China's radar technology continues to develop rapidly and is in a leading position in the world.
China's new radar has the ability to intercept hypersonic missiles, providing a strong guarantee for the country's strategic security.
And Chinese scientists have also made a major breakthrough in the field of weather radar technology, which is able to use existing weather radars to detect high-altitude balloons similar to the F35.
【Conclusion】
The development of China's radar has gone through a difficult process from scratch, from catching up to leading, and through continuous technological innovation and independent research and development, it has now become the world's leading radar power and power.
In the future, with the continuous progress of science and technology, I believe that there will be new breakthroughs in China's radar technology......
