摘　　要：多径效应是影响舰载雷达探测性能的重要因素之一。结合舰载雷达实际工作环境,构建了镜面反射与漫反射复合多径模型,推导了复合传播因子的理论表达式,仿真验证了其莱斯分布规律,对比分析了不同海况下不同类型雷达的镜面多径和复合多径效应,对是否考虑漫反射分量给出了相应建议,为舰载雷达设计、使用及性能评估提供了参考。Multipath effect is one of the important factors that affect the detection performance of shipborne radar.Combined with the actual working environment of shipborne radar,a compound multipath model of specular reflection and diffuse reflection is constructed.On the basis,the theoretical expression of the compound propagation factor is derived and its Rice distribution law is verified with simulation tests.A comparative analysis is completed on the specular multipath and compound multipath effects of different types of radar under various sea conditions.Finally,suggestions on whether to consider diffuse reflection components are offered,which provide a reference for the design,use and performance evaluation of shipborne radar.
