    Abstract: A transmitter transducer projects a short time pulse of acoustic energy which impinges upon the progressively insonifies a target area to be viewed. Acoustic returns are received by an acoustic lens which focuses the energy from individual adjacent receiver strips of the target area onto a plurality of receiver transducers located behind the lens. The output signals provided by the receiver transducers are suitably processed and displayed so as to portray the target area and any targets on it. The receiver transducers are relatively small and are arranged in a row, with the acoustic lens having at least one conical surface to provide for a variable focal length along the length thereof.

Acoustic returns are received by an acoustic lens which focuses the energy from individual adjacent receiver strips of the target area onto a plurality of receiver transducers located behind the lens. The output signals provided by the receiver transducers are suitably processed and displayed so as to portray the target area and any targets on it. The receiver transducers are relatively small and are arranged in a row with the acoustic lens being of the type which includes one or two cylindrical surfaces and arranged parallel to the target area to be viewed. Two sets of transducers may be utilized in conjunction with one lens for forming two sets of receiver beams and when mounted on a carrier vehicle, can be used for sidelooking sonar operations. Another lens and set of receiver transducers is utilized for imaging areas forward of the carrier vehicle for imaging areas missed by the other two receiver beams.

Acoustic returns are received by an acoustic lens which focuses the energy from individual adjacent receiver strips of the target area onto a plurality of receiver transducers located behind the lens. The output signals provided by the receiver transducers are suitably processed and displayed so as to portray the target area and any targets on it. The receiver transducers are elongated narrow transducers arranged in an array with the acoustic lens having one or two spherical surfaces. The output signals provided by the receiver transducers are periodically scanned for presentation to a cathode ray tube display.
