摘　　要：立足于水雷主动探测的技术发展需求 ,论述了连续小波变换、宽带相关处理以及宽带模糊度函数之间的关系 ,确定了水下主动探测发射信号及小波母函数的选取。在短程目标深测中通过选择一种满足小波条件的发射信号作为小波母函数 ,进行连续小波变换 ,估计舰船目标的运动参数 (航速和距离 )。仿真结果表明本文方法是有效的 。According to the development of the mine active detective detection technololgy, this paper discusses the relation among the continuos wavelet transforming, wide band correlation processing and wide band ambiguity function. The selections of the mother wavelet and the active signal of the mine are proposed. The movement parameters (speed and distance) of ship should be estimated by continuous transform of the wavelet of the active signal, which satisfies the factor of the mother wavelet. The emulated results indicate that the method is very efficiency and can be applied in the mine active detection..
