ABSTRACT:
A pulsed-transmission, echo-ranging sonar system of the side scanning type ses a synthetic aperture to form search beams. The system uses multiple projectors, and a multistatic hydrophone array and a four transmission sequence, each originating at the same location thus permitting a shorter array which can travel twice as fast as conventional systems while achieving grating lobe suppression.
