Abstract: In order to choose the optimal wavelet basis in the application of radio fuze, the feature of wavelet basis especially for radio fuze signal denoising is summarized, based on an analysis of wavelet basis parameter characteristics and radio fuze signal feature. A parameter namely the reconfiguration factor is introduced to judge the denoising effect, and the result obtained, i.e. the wavelet basis db12, db13 and db17 as the suitable wavelet bases for radio fuze signal denoising. The subsequent simulation test verified the correctness of the result.
