Beamforming in multipath environment using the stable components of wave field
A. L. Virovlyansky
The paper describes the beamforming procedures in an acoustic waveguide based on representing the field on the antenna as a superposition of several stable components formed by nar…
Matched shadow processing
A. L. Virovlyansky
Traditional matched field processing is based on the comparison of the complex amplitudes of the measured and calculated wave fields at the aperture of the receiving antenna. This…
Stable components of sound fields in the ocean
A. L. Virovlyansky
A method is proposed for finding the wave field components which are weakly sensitive to the sound speed perturbation in the ocean acoustic waveguides. Such a component is formed b…
Ray-based description of mode coupling by sound speed fluctuations in the ocean
A. L. Virovlyansky
A traditional approach to the analysis of mode coupling in a fluctuating underwater waveguide is based on solving the system of coupled equations for the second statistical moments…
Ray-based analysis of the interference striation pattern in an underwater acoustic waveguide
A. L. Virovlyansky
In some underwater acoustic waveguides with specially selected sound speed profiles striations or fringes of the interference pattern are determined by a single parameter β called…
Ray-based description of normal mode amplitudes in a range-dependent waveguide
A. L. Virovlyansky, A. Yu. Kazarova, L. Ya. Lyubavin
An analogue of the geometrical optics for description of the modal structure of a wave field in a range-dependent waveguide is considered. In the scope of this approach the mode am…
