摘　　要：根据舰船轴频电场信号的特点,提出了基于小波变换的目标信号检测方法。利用小波变换计算信号的功率谱,提取特征量,对信号进行滑动地目标检测。通过对海上试验采集的舰船轴频电场数据进行仿真,验证了该检测方法的有效性。According to the characteristic of the shaft-rate electric field of a ship, this paper proposes a detection method for the target signal based on the wavelet transform. The method includes three steps： the first step is to compute the power spectrum by the wavelet transform, the second step is to extract the characteristic variable, and the third one is to detect target by the sliding signal. The acquisition data of the shaft-rate electric field of a ship are simulated. The detection method is validated to be effective by the simulation result.
