Abstract : The patent describes a multi-channel sonar system which includes a liquid-lens electroacoustical transducer, a transmitter, a receiver, and an echo-range equalizer circuit connected thereto for energizing said transmitter. All sea floor echoes of the acoustical target search signals broadcast by said transducer are received at substantially the same time for all channels operating within predetermined range limits, regardless of the contour of said sea floor.
