Abstract

A side-looking sonar system utilizing an extremely long arc transducer for ultra high resolution work. The transducer is made up of a plurality of segments each connected to signal processing apparatus which electronically varies the focus of the transducer as a function of time as well as a function of transducer altitude above a target area. Additional beams, parallel to a center beam, may be formed to give the system multi-beam capability for increased search rates.
