Full waveform inversion of cross-hole radar based on wavelet adaptive filtering

摘要：

Because of its high resolution and sensitivity to underground fluid medium,cross-hole radar has attracted extensive attention.Based on the traditional ray theory,computerized tomography (CT) inversion uses only very limited information in observation data,so its application and resolution have been greatly hampered.Full waveform inversion marked the developed technique of cross-hole time domain electromagnetic inversion.Accurate estimation of excitation source plays key role in full waveform inversion,therefore,we consider noise sensitivity of convolution and deconvolution algorithm and introduce wavelet adaptive filtering methods to improve the accuracy and efficiency of source estimation.Finally,this article gives an example of numerical simulation,and full waveform inversion results were compared with the results of ray tomography,which shows that our method is valid.
