Suppressing Noise for Pseudo-random Code Fuze by overlapping addition

摘要：

How to suppress Gauss white noise that is inside the pass band of Pseudo-random code phase-modulation and pulse-doppler combined fuze is studied. According to the characteristic that Gauss white noise is stochastic, noise can be suppressed through getting the average of echo signals in several pseudo-random code cycles. The simulation results show that the ratio of maximal side lobe and main lobe of the combined fuzes correlation output is reduced evidently, and the ability of suppressing noise become stronger as the number of pseudo-random code cycles added become bigger, then through overlapping addition and get the average of echo signals in several pseudo-random code cycles, Gauss white noise can be suppressed evidently.
