Abstract

The kinetic model, describing sound propagation in the ocean with diffuse reflection by Lambert's cosine law on the bottom surface, is considered. The inverse problem of bottom scattering reconstruction is formulated. The inverse problem is reduced to solving the Fredholm integral equation of the first kind. An iterative algorithm is developed. Numerical experiments for reconstruction of the seabottom scattering coefficient depending on different width of directivity pattern are carried out.
