A model for the matched filter response to continuous reverberation from the transmission of broadband waveforms is developed. The application is for reverberation from a rough interface, based on perturbation theory. The model is developed for both the stationary rough bottom and the moving ocean surface interfaces. The mean reverberation is predicted as a function of the Doppler speed of the matched...
A physical model for clutter from rough interface scatter in low frequency active sonar systems is developed. Perturbation theory relates the mean scattering strength from a rough surface to the mean rough surface wavenumber spectrum at the Bragg wavenumber. Perturbation scattering theory is generalized to relate the clutter statistics to statistics of the interface surface roughness spectrum evaluated...
