Space debris detection imaging and communication system

Abstract

A space debris detection imaging and communication system belongs to the technical field of space target detection and information transmission and comprises a space debris detection and tracking subsystem, a coarse communication tracking subsystem, an imaging and fine communication tracking subsystem and a tracking rotary table subsystem, wherein the space debris detection and tracking subsystem, the coarse communication tracking subsystem and the imaging and fine communication tracking subsystem are placed on the tracking rotary table subsystem; the optical axes of the space debris detection and tracking subsystem and the imaging and fine communication tracking subsystem are in parallel, and the space debris detection and tracking subsystem and the imaging and fine communication tracking subsystem are arranged in parallel; the optical axes of the coarse communication tracking subsystem and the imaging and fine communication tracking subsystem are perpendicular; the reflective direction of a half-reflection half-transparent swing mirror in the coarse communication tracking subsystem aligns at the receiving direction of the imaging and fine communication tracking subsystem. According to the invention, laser ranging, imaging detection and laser communication are highly combined through optical-mechanical structure design, so that multifunction integration of measurement, imaging and communication on space debris is realized.

Description

technical field [0001] The invention belongs to the technical field of space target detection and information transmission, and in particular relates to a space debris detection system. Background technique [0002] With the increase of human exploration space activities year by year, the existence of space debris seriously threatens the safety of orbiting spacecraft. It is of great significance to monitor space debris and quickly return its information. At home and abroad, research has been carried out in two aspects: the combination of laser communication and ranging, and the combination of laser communication and imaging. [0003] 1. Research on the combination of laser communication and ranging [0004] The American X2000 flight terminal is a multifunctional instrument that not only can complete two-way communication, but also has functions such as two-way laser ranging and laser altimeter. In the structural design of the flight terminal, the ranging and communication ...
