摘要
提出多分量瑞利波勘探技术的新思路，分析了噪声对相速度测量精度的影响，建立了用极化滤波提取有效瑞利波信号的方法。处理及分析表明：多分量瑞利波勘探与单分量法比较，勘探的可靠性有所提高。
The new technique thinking of multicomponent Rayleigh wave exploration (MCRE) is put for ward firstly. The effect of phase valocity on measuring precision caused by noise is analysed.Based on polarization analysis of Rayleigh wave signal, the method of extracting effective Rayleigh wave signal by polarization filter is set up. Processing and analysis show that reliability as compared with old method of singlecomponent.
