摘　　要：面向全球导航卫星系统(Global Navigation Satellite System,GNSS)信号的外辐射源雷达,是一种利用环境中GNSS信号作为非合作照射源进行探测的雷达。为满足基于GNSS信号的外辐射源雷达系统仿真和信号处理算法设计评估的需要,通过对该雷达系统组成与工作原理的分析,完成了面向GNSS信号的外辐射源雷达软件化信号模拟器的设计与实现。给定仿真场景下软件化模拟器输出信号处理和分析的结果验证了该模拟器可根据输入参数与模型正确完成信号仿真。The passive radar,oriented on the global navigation satellite system(GNSS) signals,is a radar which uses GNSS signals in the environment as the external non-cooperative illuminator to perform detect.In order to meet the needs of simulating the GNSS passive radar system and designing the signal process algorithm,a software signal simulator of the radar system is designed and implemented after discussion of the composition,structure and working principle of the system.Finally,the output signal processing and statistical analysis result of the simulator in a designed scenario verifies that the simulator can correctly simulate the signal according to the parameters and models determined by the input.
