Attack and defense are the existence of a pair of needles against the wheat. When there is a spear, there is a shield. With the emergence of a new type of weapon, another weapon must be born to deal with it. Stealth technology and anti-stealth technology have shown a tendency to alternately rise.
During the Gulf War, the F-117A stealth fighter took the lead and became the only fighter in the multinational air force that could evade Iraqi radar surveillance and break through the dense air defense fire to enter Baghdad to carry out assaults. The 44 F-117A stealth fighters equipped in that war accounted for only 2% of the total number of aircraft of the multinational force and only 1% of the total number of sorties, but the targets destroyed accounted for 40% of the total number of targets destroyed by the air force of the multinational force. This is closely related to its excellent stealth performance and unique tactical characteristics.
In view of the outstanding performance of the F-117A stealth fighter in the Gulf War, countries all over the world are committed to the research of stealth and anti-stealth technology in order to take the initiative in this military technology field. At present, the two most commonly used stealth technologies for combat aircraft are to reduce the intensity of radar reflections and weaken infrared radiation. Following the development of stealth aircraft, some countries have developed stealth warships and stealth tanks.
After stealth technology was used, anti-stealth technology appeared immediately. The essence of anti-stealth technology is to find the weak link of stealth technology and then attack it. In view of the fact that it is impossible for stealth technology and equipment to achieve complete stealth and still have certain radar echoes, the current anti-stealth technologies mainly focus on: establishing airborne, space-based (satellite, etc.) radar systems to detect from multiple angles Stealth aircraft; use a radar with a new working wavelength to expand the working band range; increase the transmission power of the radar, such as the application of high-power active phased array radar, to improve the detection rate of stealth aircraft and other targets.
In the past 20 years, the development of anti-stealth technology has advanced by leaps and bounds. However, since the aircraft's stealth technology has reached a very high level, it is difficult to make big progress, but it has made progress in application maturity and cost reduction. In the face of a new generation of anti-stealth equipment, the advantages of stealth aircraft are being weakened little by little. At present, the number of countries in the world that apply the latest anti-stealth technology to air defense security nets continues to increase, and the struggle between stealth and anti-stealth technology will become increasingly fierce.
