Space laser communication ground test simulation platform

Abstract

The invention discloses a laser space communication ground test simulated platform. The platform comprises an A-end telescope, an A-end light splitting light path, an A-end pointing error source simulator, an A-end far field receiving simulator, an A-end collimating light path, an A-end atmosphere channel simulator, a B-end back light simulator, an AB beam combination light path, a B-end vibration-relative movement simulator, a B-end light splitting light path, a B-end telescope, a B-end pointing error source simulator, a B-end far field receiving simulator, a B-end collimating light path, a B-end atmosphere channel simulator, an A-end back light simulator, a BA beam combination light path, an A-end vibration-relative movement simulator, and a computer central processing unit (CPU); and the platform also comprises a first light path turn plane reflector and a second light path turn plane reflector. The laser space communication ground test simulated platform has a compact overall structure, occupies small space, can realize terminal system test for direct alignment of multiple parameters in short distance of two communication terminals, and can simulate multiple external factors affecting laser space communication performance.

Description

technical field [0001] The invention relates to the field of space laser communication, in particular to a ground test simulation platform for space laser communication. Background technique [0002] As a payload, the space laser communication system must be strictly tested for its main technical indicators and performance parameters, such as tracking and targeting accuracy, acquisition characteristics, and communication error codes, no matter after the development is completed or before launch. rate etc. Generally, the distance of space laser communication is hundreds of kilometers to hundreds of thousands of kilometers, or even farther, while the diameter of optical transceivers is several centimeters to tens of centimeters, so the reception of optical signals is far-field reception. The space laser communication ground test can be divided into system level test, subsystem or module level test and component level test. The transmitting terminal and the receiving terminal...
