摘　　要：为了对空中/空间高速运动非合作目标辐射信号进行稳定接收,采用单脉冲跟踪体制,设计了一套被动无线电信号接收系统。针对单脉冲自动跟踪的相位检查,利用太阳辐射源解决了实装系统全频段全时校相问题。文中提出了一种多维度的目标信号自动跟踪联合制证准则,解决了信号参数、出现时间、出现空域均未知的非合作信号快速捕获与自动跟踪问题。通过某国空间非合作目标辐射信号的实收试验,证明系统可以在10 s内实现稳定自跟踪,验证了设计的有效性。According to the stable reception of radiation signals from high-speed non-cooperative targets in air or space,a passive radio signal receiving system is designed by using single pulse tracking system;Aiming at the phase inspection of single pulse automatic tracking,the problem of full-frequency and fulltime phase correction of the actual system is solved by using solar radiation source;A multi-dimensional joint criterion for automatic target signal tracking is proposed,which solves the problem of fast acquisition and automatic tracking of non-cooperative signals with unknown signal parameters,occurrence time and occurrence space. Through the actual receiving test of the radiation signal of a space non-cooperative target in some country,the system can realize stable self-tracking within 10 s,which verifies the effectiveness of the design.
