ABSTRACT:
A phased array sonar is arranged to obtain an image in a wide field of view beyond a normal angle of view. In an angle of view beyond the normal angle of view, the number of active transducer elements, which are simultaneously energized, is reduced, as the angle of view is increased, and at the same time, the amplification factor for the echo signals is increased.
