摘　　要：针对地面射频设备由于信号衰减必须束缚在被测卫星周围的问题,将光纤载射频技术(RoF)引入到小卫星综合测试领域,设计小卫星智能综合测试系统。该系统包括一体化智能测试软件、射频信号处理中心、光缆、射频信号远端接入点,以及总控测试设备(OCOE)软件和各分系统专用测试设备(SCOE)。通过光电转换实现射频信号的远距离传输,改变地面射频设备各自为营的分散式测试模式,解决测试过程中射频测试设备布局不合理、共享不方便、需要频繁搬运的问题,从而降低测试成本,提高小卫星的测试效率。In response to the problem that ground RF(radio frequency)equipment must be tied up around the satellite due to signal attenuation.The RoF(RF over fiber)technology is introduced into the field of small satellite comprehensive test,and an intelligent comprehensive test system for small satellite is designed.The system includes integrated intelligent test software,RF signal processing center,optical cable,RF signal remote access point,as well as OCOE(overall checkout equipment)software and subsystem SCOE(special checkout equipment)for each subsystem.It realizes the long-distance transmission of RF signal through photoelectric conversion,and changes the decentralized test mode of ground RF equipment.It solves the problem of unreasonable layout,low efficiency sharing and frequent handling during test.The system thereby reduces test costs and improves test efficiency of small satellites.
