| Abstract: | The inverse problem of SH wave propagation in horizontally stratified elastic medium is discussed in this paper. The medium velocity, density and thickness are inversed layer by layer using arrangement and combination and transfer operator technique in the plane pulse SH wave source excitation in the reflectivity method. The inverse progress is transformed a linear regression. The numerical simulations are performed. The inverse method of layer by layer cuts down equation rank and calculation quantity. |
