Formulae for bistatic signal and reverberation

Abstract

This report demonstrates that it is possible to obtain closed-form solutions for signal and reverberation in a wide variety of bistatic scenarios including ducts and bottom bathymetry. These formulae adapt earlier monostatic solutions [SACLANTCEN Reports SR-356, SR-370, SR-358]. Examples are given for bistatic reverberation with the source and receiver near a shelf at the top of a slope. Results are presented both mathematically and graphically as plots of reverberation vs delay time and bearing and reverberation in map projection.
