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.
