摘要
针对目前国内卫星直扩跳频(DS/FH)测控(TT&C)系统测试不全面,测试方法通用性差的问题,通过分析DS/FH测控系统工作特点和测试技术难点,提出了一种卫星DS/FH测控系统自动化测试方法,并设计了一种基于软件无线电和通用仪器的通用自动化测试系统。该方法充分模拟天地测控链路环境,可综合、全面、灵活地考核DS/FH测控系统的捕获性能、动态性能和抗干扰性能。在某卫星整星各测试阶段进行了应用,结果表明:该测试方法准确可行,测试全面、充分、通用性好、可重构能力强、测试效率大幅提升,可推广到各类卫星DS/FH测控系统测试中应用。
Aiming at the problem that the domestic satellite direct sequence spread spectrum/fre-quency hopping （DS/FH ） telemetry tracking and command （T T ＆ C ） system is incompletely tested and the test methods are not universally applicable. An automatic test method for satellite DS/FH TT＆-C system is proposed by analyzing the working characteristics and test technical dif-ficulties of the DS/FH TT＆C system, and a generic automated test system based on software ra-dios and general-purpose instruments is designed. This method fully simulates the environment of TT＆C radio link between satellites and the ground station, and can comprehensively and flexibly evaluate the capture performance, dynamic performance and anti-jamming performance of DS/FH TT＆C system. This method has been applied at each test stage of a satellite, the results show that the method is accurate and feasible, and the test is comprehensive, sufficient, versatile, and has strong reconfigurability and test efficiency. It can be applied to some kinds of satellites for the test of DS/FH TT＆C system.
