箔条云雷达回波的仿真研究

通过建立箔条干扰下的雷达回波模型,根据回波产生的机理,模拟出回波的幅度服从瑞利分布,相位服从均匀分布。根据统计学原理,推导出箔条云雷达回波的功率谱密度,服从高斯分布。结果与实际相符,说明了该仿真方法的正确性。通过仿真比较和分析了当箔条云中含有静态或动态目标时的雷达回波、幅度分布和相位分布。对箔条干扰研究具有重要意义。

Research on Simulation of Radar Echo from Chaff Cloud

According to the echo’s mechanism of generation,it can be simulated that the chaff echo’s amplitude obeys Riley distribution and phase obeys equal distribution,through building the radar echo model under the chaff jamming.Based on the principle of statistics,the power spectral density of the radar echo from the chaff cloud can be gained,which obeys Gauss distribution.The result conforms to the fact,which proves the correctness of the simulation method.The radar echo,amplitude distribution and phase distribution are compared and analyzed when there is immobile or kinetic target in chaff cloud,which has important meaning to the research of chaff jamming.
