Abstract

The leakage noise of the pseudo-code phase modulation fuze system is the noise interference caused by the insufficient isolation of the radio frequency part. Since the leakage signal is similar to the echo signal waveform, it will affect the output of the correlator and lead to misjudgment of the fuze. In this paper, the pseudo-code phase modulation fuze's emission leakage signal is modeled, and its characteristics are analyzed, and an adaptive noise cancellation method for the pseudo-code phase modulation leakage signal is proposed. The algorithm simulation shows that the noise filtering effect is good. Pseudo-code phase modulation fuze prototype is used to actually test the algorithm. The algorithm can increase the correlation peak value of the actual target signal and reduce the influence of leakage noise and natural noise floor.
