Title :
Use of frequency and transmitter location diversities for ambiguity suppression in synthetic aperture sonar systems
Author_Institution :

Abstract :
Three synthetic aperture sonar designs, which aim at doubling the mapping rate by use of transmitter location and frequency diversities, are assessed. It is shown that neither allow better ambiguity suppression than the conventional design. Two new designs, M. A. Pinto (1996), which achieve this goal are presented as well as an extension to bathymetric imaging. An application to deep ocean imaging is proposed
