| 摘 要： | 无线电测向设备是无线电侦查设备的重要组成部分之一，无线电测向是利用无线电测量设备测定目标信号的方位信息。在测向试验中由于周围环境的不同，当有二次反射体存在时，将引起多径效应，使得来波方向呈现不唯一性。在对两径传播模型分析的基础上，进而分析三径传播对测向方位角的影响，并通过计算机对三径传播进行仿真，总结多径效应对测向方位角的影响规律。

| Abstract: | The radio direction finding device is an important part of the radio-detection equipment, and it uses radiomeasuring equipment to get the orientation information of the target signal. The environment of the direction finding experiment is different, so when there are secondary reflector exist, multipath effects would be caused, which makes the DOA does not render unique. In this paper, analyze the two-ray propagation model. On this basis, analyze the influence of the direction finding azimuth, which caused by the three-ray propagation. The computer simulation is carried out, and summed up the rule, that is the influence of the direction finding azimuth, which caused by the multi-path effect. |
