摘　　要：从多径效应存在的物理意义出发 ,建立了多径效应的模型。在此基础上 ,分析了在特定条件下多径效应对系统检测性能的影响 ,推导了弹载毫米波In this paper, a multi path effect model is built up from its physical significance. Then the influence of the multi path effect on the detection performance of a system under some specific conditions are analysed, and further the relationship between the multi detection distribution of the multi path effect factor μ and the detection performance of the M/N detection approach is derived while a missile borne milimeter wave PD radar is used to detect a hovering helicopter.
