Abstract
Radiation propagation in the ocean is described using mathematical model based on the radiation transfer equation. Solution of the direct problem for determination of the flux density is obtained in the double scattering approximation. The inverse problem is formulated as determination of the function describing the deviation from a reference value. As a solution for the inverse problem, a nonlinear differential equation is obtained with some assumptions on the radiation pattern of the receiving antenna. A numerical algorithm is developed and computational experiments are carried out with various types of seabed surfaces. The effect of double scattering on the seabed topography restoration is analyzed.
