摘要
本文提出了一种二次雷达信号的盲分离算法,该算法遵循盲源分离的理论,并假设各信号之间与噪声之间存在相互独立的关系,通过分析二次雷达信号的ZCM(零/横模)特征,采用一种用于二次雷达分离的低价函数,并将其对应的单脉冲比求解得到混合矩阵和分离矩阵,最终实现对二次雷达信号的有效分离,避免了传统算法考虑滤波理论分离雷达信号的复杂性,当信噪比不低于20d B时可被广泛使用。
In this paper, a blind separation algorithm for two radar signals is proposed. The algorithm follows the theory of blind source separation, and assumes that there is an independent relationship between the signals and the noise. By analyzing the characteristics of the ZCM（zero/transverse mode） of the two radar signals, a low price function for the separation of the two radar is adopted, and it corresponds to it. The monopulse ratio is solved to get the mixed matrix and the separation matrix, and the effective separation of the two radar signals is finally realized. It avoids the traditional algorithm considering the complexity of the filtering theory to separate the radar signal, and can be widely used when the signal to noise ratio is not less than 20 d B.
