Recently, the Japanese media reported that although the number of Chinese warplanes is five times that of Japan, the battle will be defeated. The basis is that the radar performance gap between the two is obvious. Air Force equipment expert Song Xinzhi said in an interview with Beijing TV’s “Military Intelligence Decoding” that this analysis is biased. The impact of missile performance in air combat is greater than radar performance, and in this respect, Japan is an order of magnitude behind China.
It is a distant past for fighters to rely solely on the cabin and the mobility of speed performance and hovering performance to determine the outcome of air combat. Modern warfare is a kind of sensor that quickly senses distant threats, then processes the information through the computer, and then provides the processed information to the pilot, so that it can make the most appropriate action as quickly as possible, and achieve multi-machine interaction. Information sharing. According to the report, in terms of these performances, the US F-35 is the most popular, followed by the F-22, because they are equipped with AESA radar, and have a LINK-16 data link to achieve sensor fusion.
According to reports, the so-called AESA radar mentioned by the Japanese media is also called active phased array radar. The United States started early in the field of active phased array radar technology and is investing early. A big lead. The current US military fighters are equipped with organic and active phased array radars. The most typical one is the US F-22, and the active phased array radar is used on the fighters for the first time.
Some analysts believe that the biggest breakthrough of the F-22 is that its avionics system achieves a higher degree of integration, and the active phased array radar is first adopted in fighter aircraft, which makes the F-22 more For the sharp “eyes”, more rich combat functions, the distance of the fighter target is more than 200 kilometers, which can achieve the first enemy discovery, the first enemy launch, the first enemy hit. Active phased array radars can perform fast scans, making it difficult for the enemy to detect and locate. At the same time, electronic intelligence collection can be carried out to achieve interference monitoring and communication. These are not possible with previous fighter radars.
Song Xinzhi pointed out that the current assessment of the air combat capability of fighters is the first, but its influence is minimal. The second is the radar detection range, including the detection distance of the photoelectric system, and the factor that is more influential is the missile. He said that the Japanese fighters have strong maneuverability and strong radar performance, but the range and attack capability of air-to-air missiles are much weaker than that of China’s air-to-air missiles. The difference between the two is an order of magnitude.
& ldquo; We can imagine that your radar looks very far, but the missile launch distance is very close. If the other side’s missile is farther away than you, the person will hit you first, and it will be the missile that is not fired after the launch. After the evacuation of the launch site, you will not have a transmitter. Therefore, the missile’s attack distance is the first in the air combat capability evaluation. ” Song Xinzhi said.
