Optimization of the inverse problem algorithms of reconstructing geo acoustic parameters of bottom layers by coherent sounding

Methods and algorithms of lay-by-lay reconstruction of geo acoustic parameters of bottom layers with use of parametrical models of formation of the signals reflected from layered semi space at coherent sounding of a bottom of a sea shelf are analyzed. The method of reconstruction, allowing to carryout effective search of the decision in multiple parameter space is offered at restriction of the aprioristic data. By methods of stochastic modeling it is investigated robust algorithms of reconstruction.
