Study of wavelet operator on eliminating direct waves in GPR

The paper presents how to design optimal wavelet operator that adaptively eliminate direct waves (DW) of ground penetrating radar (GPR). It is well known that there are many wavelet operators in known wavelet family so that it is important problem to select optimal wavelet from the wavelet family. Based on transcendental information of DW in GPR and under matched rule, the paper gives the method on design optimal weight wavelet operator. The experimental results by raw data of GPR show that the method on presented design of wavelet operator in paper is effective to remove DW in GPR.
