摘　　要：多径效应是被动测向过程中客观存在的现象,基于其产生的物理机理可从角闪烁的观点出发来加以讨论。首先介绍了角闪烁的两种物理解释,其次对被动测向中的多径效应进行了一般的数学分析,说明了相应的统计模型,重点对低仰角时被动测向中的多径效应进行了特例分析,并进行了数字仿真。The multipath effect is objective in passive direction finding and can be discussed from glint consideration.Two concepts of angular glint are introduced firstly,and then the multipath effect in passive direction finding is mathematically analyzed in general and its statistical model is described.Finally,the multipath effect in passive direction finding at low elevation is analyzed particularly and simulation results in this situation are given.
