Inverse scattering for geophysical problems. II. Inversion of acoustical data

An algorithm is given for finding the density and bulk modulus (refraction coefficient) of an inhomogeneity from the knowledge of the scattered field on the surface of the earth for all positions of the source and receiver on this surface and for two arbitrary fixed frequencies in the Born approxima...

description An algorithm is given for finding the density and bulk modulus (refraction coefficient) of an inhomogeneity from the knowledge of the scattered field on the surface of the earth for all positions of the source and receiver on this surface and for two arbitrary fixed frequencies in the Born approximation. An alternative inversion method using the low‐frequency data is also given.
