Abstract
A sonar system including an elongated transducer having a fully populated or non-fully populated array of transducer elements. During course of travel of the carrier on which the transducer is mounted, successive acoustic transmissions take place whereupon the transducer elements provide output signals in response to the reflected energy. At least one synthetic aperture beam is formed by combining the element output signals from at least two successive transmissions wherein there is a predetermined gap between the array at a location at which a first transmission takes a location at which a subsequent transmission takes place.
