Application of the Discrete Wavelet Transform in the Ranging Algorithm of Radio Fuze

摘要

Echo signal of radio fuze is a special transient signal whose wave parameters and arrival time are unknown. In this paper, an echo detection method of radio fuze based on discrete wavelet transform is introduced. The method adopts special wavelet basis function and scale factor, and obtain signal arriving time to realize distance measurement by the relationship that discrete wavelet coefficient of echo signal arrives peak at the corresponding time.Simulating results show that the method is feasible in radio fuze ranging application.
