Anti satellite weapons are space weapons that strike, destroy spacecraft or damage their normal functions. Generally speaking, there are four types of anti satellite weapons: common orbit, direct ascent, directional energy and electromagnetic interference. According to the location, it is divided into ground-based anti satellite weapons and space-based anti satellite weapons; According to the means of killing, it is divided into nuclear ASAT weapons, kinetic ASAT weapons and directional energy ASAT weapons.
[classification]
Ground based nuclear ASAT weapons and kinetic energy ASAT weapons can be divided into two types: common orbit type and direct ascent type. The interception satellite adopts the common orbit interception mode. Its operation process is: launch the satellite with blasting device to the orbit basically the same as the orbit of the target with the carrier rocket, then use the satellite radar or infrared seeker to detect and track the target, and rely on the small rocket engine to maneuver and change the orbit to approach and destroy the target; The anti satellite missile adopts the direct ascending interception mode. Its operation process is: multi-stage missiles with nuclear or non nuclear warheads can be directly launched from land, sea or air to the airspace near the target, and then use the automatic homing guidance device on the missile to detect and track the target. When the missile approaches the target at a certain distance, start the warhead's explosive device to destroy the target, or use the kinetic energy of the warhead's high-speed movement to crash the target.
Space based anti satellite weapons are divided into common orbit anti satellite weapons and non common orbit anti satellite weapons. Tianlei is a common orbit anti satellite weapon. It is a device secretly set on the target track with some means of killing or destruction. If necessary, it can quickly approach and destroy the target by means of radio remote control, or release metal particles, debris, aerosols and other interferences to destroy the target. Non common orbit anti satellite weapons refer to kinetic energy weapons and directional energy weapons installed on spacecraft. The directional energy anti satellite weapon destroys or loses its working ability by irradiating the target with high-energy laser beam, particle beam or microwave beam.
[function]
The main function of anti satellite weapons is to attack the enemy's low orbit military satellites in space war, especially the enemy's reconnaissance satellites, marine surveillance satellites and navigation satellites, and undermine the enemy's ability to obtain intelligence and command operations from space.
