摘　　要：为了探讨机载反舰导弹在多径环境下对接收机的影响,结合机载和弹载雷达的工作环境,构建镜面反射复合多径模型,仿真了机载和弹载雷达信号的时频图、CW时频分布图和MBD时频分布图,分析了不同阶段下雷达的时频特征,得出MBD时频分布图所受多径效应影响最小的结论,为舰艇自适应反导提供了参考信息。In order to discuss the influence of airborne anti-ship missile on the receiver in the multipath environment,a mirror reflection composite multipath model was constructed combining the working environment of airborne and missile-borne radar.The time-frequency diagram,CW time-frequency distribution diagram and MBD time-frequency distribution diagram of airborne and missile-borne radar signals were simulated,and the time-frequency characteristics of the radar at different stages were analyzed.It is concluded that the MBD time-frequency distribution is least affected by multipath effect,which provides reference information for ship adaptive anti-missile.
