Abstract
A side-looking sonar is provided with the wide angle acceptance characterics of a wide receiving beam together with the high resolution of a narrow receiving beam, while retaining both echo and shadow detection capability, through the use of a plurality of transducers disposed at such angles that their respective narrow beams cross one another at a location between the transducers and the ranges of interest and the distal portions of the beams lie adjacent one another. Individual returns received from the beams as the sonar is moved along a path normal thereto are coherently combined and detected.
