在被动雷达导引头主波束内同时存在目标雷达和噪声干扰源的情况下,利用传统的单脉冲比进行测角会带来很大的误差。针对噪声源为噪声调频干扰以及高斯噪声的情况,利用雷达信号本身的自相关性强、噪声信号本身的自相关性差以及雷达信号和噪声信号之间互相关性差的特点,提出了基于信号相关的抑制噪声源干扰的方法。通过计算机仿真对该方法的性能进行了分析。
Abstract：When there is a target radar and a noise interference source in the mainlobe of a passive radar seeker,serious error may occur by using the traditional monopulse ratio method for angle measurement.For noise frequency modulation source and gauss noise interference source,a method based on signal correlation is proposed to eliminate the effect of noise interference based on the strong autocorrelation of radar signal,weak autocorrelation of interference noise and weak cross correlation between the two.And the performance of this method is analyzed by computer simulation.
