| 摘 要： | 针对利用地震波场对目标进行探测问题，研究了利用地震波勘探的基本原理，提出了采用小波变换对地震波信号进行降噪的方法，通过与传统的经典滤波方法相比，小波变换降噪方法在去除掉高频噪声的同时保留了信号的高频成分，是一种比傅立叶变换更有效的降噪方法。对比了几种小波去噪的方法，从不同的性能指标中优化出针对地震波信号的环境特点最为有效的降噪方法，从而达到有效提取有用信号并探测目标的目的。

| Abstract: | In order to solve the problem of detecting target by a seismic wave field, a noise reduction approach using wavelet transform is proposed. a special wave model-surface wave is used and the principle of detecting buried target is studied. The method in which wavelet transform is capable of reducing the noises in seismic wave signal is presented. So distilling the useful signal and detecting the buried target by seismic wave field signal can be realized. |
