摘要
根据MIMO雷达比幅法测角原理,提出了一种对MIMO雷达进行角度欺骗干扰的方法。此方法是在两点源相干干扰的基础上,根据MIMO雷达测角特点做出修正而成。在MIMO雷达相邻波束内布置2个干扰站接收雷达信号,进行调幅和调相后作为干扰信号转发出去,通过控制干扰信号的幅度和相位,使雷达测量的目标角度偏离真实角度,从而达到角度欺骗干扰的目的。理论分析和仿真结果验证了此方法的有效性。
Based on the theory of amplitude comparison angle measurement of MIMO radar,a method is established to make the angle deception jamming to MIMO radar.This method is on the basis of dual-source interference,and correct for the features of MIMO radar.Two jamming station are arranged in the neighbor beams of MIMO radar,receiving radar signals and transmit them after amplitude modulation and phrase modulation.The target azimuth that the radar measures will be different from the real azimuth through controlling the amplitude and phrase of jam signals.Theoretical analysis and simulation result show the effectiveness of this method.
