Sonar receivers
First Claim
1. A sonar receiver, comprising an inwardly curved reflector arranged to direct received sonar signals onto a transducer system, which transducer system comprises an array of transducers distributed over an inwardly curved path facing the reflector such that each transducer is directed towards the center of the reflector and 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.

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.
