相干干扰下无源测向系统方位测量误差模型

摘要

In order to evaluate coherent jamming effect on passive direction-finding system quantificationally,direction-finding error of two typical passive direction finding system was deduced under the circumstance of coherent interference. Simulation results and analysis showed that the changing trend of direction finding error of passive direction finding system under coherent interference and the convention were equal.%为了定量评估相干干扰对无源测向系统产生的干扰效果,推导了相干干扰情况下两种典型无源测向系统的方位测量误差.仿真分析表明:相干干扰下无源测向系统方位测量误差的变化趋势与常理是相符的.
