水下目标信号特征提取与采集研究

Research on Feature Extraction and Collection for Underwater Target Signal

提出了基于子波变换的辐射噪声特征提取方法 ,据此获得了水下目标的有效频率分布范围 ,为水下目标信号采集器的设计确定了频率范围 ,同时介绍了水下目标信号采集器的硬件结构、实现方法和实验结果。

A kind of radiated noise feature extract method based on the wavelet transform has been provided in this paper, hereby, the efficiency frequency distribution range about the underwater target has been acquired. It has been used to define the operation frequency range for underwater target signal collector. The hardware design and experiment result for the collector has been introduced in this paper.
