ABSTRACT:
A sonar receiver comprises an inwardly curved reflector arranged to direct received sonar signals onto a transducer system. The transducer system comprises an array of transducers distributed over an inwardly curved path facing the reflector. Each transducer is responsive to sonar signals received from a particular direction to provide an output signal indicative of a reflecting object, the amplitude of which signal is related to distance of the reflecting object.
