In the research of elastic wave signal detection algorithm,a method based on adaptive wavelet analysis and segmentation threshold processing of the channel noise removal methods is suggested to overcome the effect of noise,which is produced by absorption loss,scattering loss,reflection loss and multi-path effect during the elastic wave in the transmission underground.The method helps to realize extraction and recovery of weak signal of elastic wave from the multi-path channel,and simulation study is carried out about wavelet de-noising effects of the elastic wave and obtained satisfactory results.
