Abstract

Rayleigh wave is a secondary wave characterized by low frequency and strong energy,propagating mainly along the interface of medium and rapid attenuation of energy with increase in interface distance.The same as reflected wave and refracted wave,Rayleigh wave also contain subsurface geological information. In this paper, the concept of the Rayleigh wave, wave equation, dispersion equation, the frequency bulk characteristics and the application of the actual data are used to indicate the characteristics of Rayleigh wave and its application. According to the seismic wave field characteristics, analyzed further about the seismic wave in the form of noise and denoising method,focus on the analysis of the polarization filtering method to extract Rayleigh wave which is based on covariance matrix as the basis for the realization.
