摘　　要：海面多径效应是影响舰载电子战接收机性能的主要原因之一。研究了海面多径效应对瞬时测频接收机性能的影响,分析了瞬时测频接收机的基本原理,建立了海面多径效应对瞬时测频接收机性能影响的理论模型,并对反射信号个数、功率、相位等带来的影响进行了仿真。Surface multipath effect is one of main factors influencing the performance of shipborne electronic warfare receiver.This paper studies the influence of surface multipath effect on the performance of instantaneous frequency measurement（IFM）receiver,analyzes the basic principle of IFM receiver,establishes the theory model for the influence of surface multipath effect on the performance of IFM receiver,and simulates the influence caused by the number,power and phase etc.of reflected signals.

关 键 词：多径效应 瞬时测频 接收机性能
