Featured researches published by A. G. Nechaev.

Radiophysics and Quantum Electronics | 1996

Interferential algorithm for ocean bottom diagnostics

A. Yu. Kazarova; L. Ya. Lyubavin; A. G. Nechaev

The efficiency of determining sound velocity, sound density, and acoustic attenuation factor in the bottom is evaluated by a numerical experiment, using the method of interferential ocean bottom tomography proposed by the authors. Simulation is performed in the presence of random noise when the source power is unknown.

Acoustical Physics | 1994

A ray scheme of a differential method for ocean acoustic tomography

A. G. Nechaev; V. N. Fokin; M. S. Fokina

Acoustical Physics | 1995
