Laser anti-satellite system based on satellite-borne deformable mirror and control method of system

Abstract

The invention discloses a laser anti-satellite system based on a satellite-borne deformable mirror and a control method of the system and belongs to the field of photoelectric tracking. The system comprises a ground-based laser and a satellite-borne deformable mirror system, wherein the deformable mirror system comprises parts such as a mirror two-dimensional driving mechanism, the deformable mirror, a mirror bracket, regularly hexagonal plane mirror two-dimensional driving mechanisms, a square facula-based four-quadrant detector, a target detector, a computer and the like; the deformable mirror is formed by assembling a plurality of regularly hexagonal plane mirrors, the two-dimensional driving mechanisms are mounted at backs of all the plane mirrors, and the four-quadrant detector is mounted in the center of the deformable mirror; the computer acquires position information of an enemy target and the ground-based laser, converts the position information into the azimuth angle and the pitch angle and controls the mirror two-dimensional driving mechanism and the plane mirror two-dimensional driving mechanisms to adjust the azimuth angle and the pitch angle, so that all the regularly hexagonal plane mirrors enable reflected light beams to be aligned to the target; the ground-based laser emits intense laser to destroy the target after tracking stabilization is realized.

Description

technical field [0001] The invention relates to a laser anti-satellite system based on a space-borne deformable mirror and a control method thereof. Background technique [0002] Laser anti-satellite weapons take the form of light beams, which are fired in a certain direction through the combined effects of high heat, ionization, shock and radiation to kill satellites. Its light beam has the characteristics of large energy, fast speed, high precision and strong anti-interference. Regardless of the difference in the nature of the energy carrier, the weapon system has the following characteristics: First, the propagation speed of the beam energy is close to the speed of light, and it can hit once launched, and can generate the required power value for a relatively long working time, and has a good The quality of the beam energy; secondly, the beam energy is concentrated, and the laser beam is gathered very thinly, so that the enemy has no time to maneuver, avoid or fight.

Problems solved by technology

However, ground-based lasers have many disadvantages. One is that not only the refraction of the atmosphere on long-range lasers will seriously affect the accuracy of tracking and aiming at high-speed flying targets in space, but also that the lasers will be absorbed and scattered by atmospheric molecules and aerosols when they are transmitted in the atmosphere. , its strength will decay

The second is that the influence of atmospheric turbulence will cause the spot on the ta
