The Sea Surface as a Random Filter for Underwater Sound Waves

Abstract

In this dissertation the phenomenon of scattering and reflection of underwater sound waves from the sea surface, is studied by considering the surface sound channel as a random, time-dependent filter. This filter can be best analyzed by means of its frequency transfer function, from which another important system function, the impulse response, can be derived as Fourier transform.
