摘　　要：星间天线对信号的扫描搜索跟踪是星间链路接收的首要条件。针对非合作星间链路信号高精度搜索跟踪的需求,对天线伺服搜索跟踪系统进行研究。提出基于阿基米德螺旋扫描搜索策略和步进跟踪体制的搜索跟踪算法,通过分析电平测试值和方位俯仰值,验证对非合作星间链路信号的捕获和跟踪性能。Signal scan and tracking is the primary condition of inter-satellite link signal receiving.The antenna servo system is studied in response to the needs of non-cooperative inter-satellite link signal search and tracking.A search and tracking algorithm based on Archimedes spiral scanning search strategy and the step tracking method is proposed.The acquisition and tracking of the satellite signals are verified by analyzing the measured values of signal levels and the values of azimuth and pitch.
