Abstract
We study signal-accumulation and noise-suppression methods and algorithms that improve the accuracy and stability of reconstructing the geoacoustic parameters in layer-by-layer reconstruction of bottom layers and use parametric models of the formation of signals reflected from an elastic layered half-space under coherent pulsed probing of the sea shelf bottom. We present the results of analyzing the efficiency of the algorithms by stochastic numerical simulation.
