卫星激光通信Ⅱ地面检测和验证技术

星间激光通信终端的主要技术指标和运行性能必须事先在地面实验室条件下进行模拟检验, 因此在研制卫星激光通信终端的同时必须发展相应的系统性检测和验证平台, 主要包括激光通信性能检验、光跟瞄性能检验和光束质量检验。本文综述了卫星激光通信终端检验技术的国外进展, 介绍了我们全物理模拟的地面检测验证思路和方法。

The technical specifications and the functions of a satellite lasercom terminal must be tested and verified before its launch. Thus it is necessary to build up the testbeds at the same time to develop terminals, which include the communication performance testbed, the pointing, acquisition, tracking (PAT) function testbed and the setup for testing the quality of beam wavefront. This paper reviews the international progresses on the test and verification of lasercom terminals, and presents our proposals of testbeds with fully physical simulations.
