摘　　要：为满足导弹等高速运动平台与中继卫星之间稳定的双向信息传输需求,文中给出了相控阵跟踪系统方案,并分析了相控阵自跟踪系统的关键技术,即角度搜索/捕获、角度跟踪、接收工作过程系统时序设计。相控阵二维测角是实现跟踪过程的关键,文中描述了对二维测角验证试验过程,并通过仿真实例说明影响测角精度的因素。For the requirement of the stable two-way information transmission between the platform for high-speed motion of missiles and a repeater satellite,a phased array tracking system solution is given and the key technologies of the tracking system are analysed,such as angle searching/capturing,angle tracking,the timing design of work process for receiving system.Two-dimensional angle measurement of phased array radar is the key to the tracking process.A detailed description of two-dimensional angle measurement is carried out in this paper and the factors affecting the accuracy of measurement are simulated.
