| 摘 要： | 本文针对测深数据在环境噪声处理中存在的问题,利用海底信号和环境噪声小波变换模的极大值在不同尺度下具有不同的传播特性,提出了利用多尺度小波变换分析测深数据的方法,从而达到降低环境噪声对测深数据影响的目的。通过实验表明该方法具有较好的效果。

| Abstract: | In this paper, firstly, Based on the different multiscale behaviors of wavelet transform of sea echosounding signal and environment noise in different scales at dealing with oceanic depth measurements data, the method of multiscale sounding data processing is discussed. So we could achieve to cut down noise influence. Finally, experiment of emulation data shows its better effectiveness. |
