摘要:
针对伪码引信中抗欺骗干扰的问题,提出了互相关与正交投影联合法。首先干扰作用下的伪码引信视频信号与伪码产生器产生信号进行互相关,通过门限检测法获得相关峰数目,若存在一个相关峰,不进行抗干扰处理,若存在两个相关峰,通过相关峰值检测估计干扰延时,利用该延时信息和伪码产生器产生信号获得正交投影矩阵,干扰通过正交投影被滤除。仿真分析发现该方法能有效滤除干扰,抗干扰后信号与理想回波信号基本吻合。
Abstract:
A cross-corre lation and orthogonal pro jectionmethod is presented to suppress the fraudulent jamm ing for pseudo no ise ( PN ) fuze. The received v ideosigna l is corre lated w ith the PN signal from the signal generator. The number of co rrelat ion peaks is obta ined by thresho ld detection. If there is on ly one peak, it is unnecessary to suppress jamm ing. If there are tw o peaks, the fraudulen t jamm ing time delay is estimated by corre lation peak detection. The pro ject ion matrix is obta ined by the time delay info rmation and PN signa l. The jamm ing is suppressed by o rthogonal projection. It is found by simulat ion that the above method can effective ly suppress the jamm ing. The signal after suppressing is sim ilar to the idea l v ideosignal.
