Abstract

Summary: A variety of methods has been presented to invert arrival time of seismic waves for velocity distribution over the survey area. In real world, the velocity distribution model consists of blocky structures as well as smooth varying parts. In such cases, implementation of Tikhonov Regularization will recover the smooth varying portion of the velocity model; while the Total Variation (TV) regularization is capable of recovering the blocky varying parts of the velocity model. In this research, a technique for solving Inverse Problems based on a combination of second order Tikhonov and TV Regularizations is proposed. The methods are tested on both synthetic and real arrival times and the results are presented. ...
