| 摘 要： | 介绍一种短时平均过零率的计算方法，它具有易于用软件实现和便于调整检测门限。用短时平均过零率表征连续波多普勒体制无线电近炸引信多普勒信号频率，使引信具有一定的抗干扰能力。弹目交会时目标的体目标效应显著，多普勒频率起伏较大，选用小波变换技术对其进行平滑处理，优化估计信号的频率。

| Abstract: | This paper introduces a kind of computing method about short time average zero - over rate. The fuze is provided with some Anti - jamming function by means of instantaneous time average zero - over rate representing Doppler signalt frequency of continuous wave radio Doppler system fuze. During the course of encounter of target and bomb, the Doppler Frequency varies heavy abnormally, here we optimize the frequency estimation by means of smoothness function, which wavelet transformation possess. |

| Keywords: | doppler frequency zero - over rate wavelet transform |
