摘　　要：针对单通道、单脉冲体制的自跟踪系统调试和测试需设置远场信标信号,结合天伺馈系统在外场才能完成的技术现状,设计了可同时模拟带有多普勒信号、方位误差电压信号、俯仰误差电压信号和方波调制信号的多种形式的单通道单脉冲体制的自跟踪信号源,并在实验室条件下利用模拟信号源搭建了自跟踪接收解调系统的调试、测试环境。通过试验表明,采用该种模拟仿真的方法减少了调试时间,提高了工作效率。The far-field beacon signal is required to set for single-channel monopulse auto-tracking system debugging and test,and the antenna servo and feed system is required to implement in out-field. Based on this situation, this paper designs a single-channel monopulse auto-tracking signal generator,which can simultaneously simulate a variety of signals,including Doppler signal, azimuth error voltage signal, elevation error voltage signal and square wave modulation signal.Moreover, the debugging and testing environment of auto- tracking receiving demodulation system based on analog signal generator is constructed in the laboratory.The test results show that this simulation method can shorten the debugging time and improve the work efficiency.
