    Abstract: The invention provides a sonar system having a moving window display of the sonified area in which a single broad beam projecting transducer is employed to sonify a desired area. A plurality of line focus receiving transducers are used to receive signals from adjacent strips of the sonified area, and the signals received from each transducer are amplified, detected and sampled. A sampling switch is employed to sequentially sample each detector channel RE times, where RE represents the number of range elements. The sampled signals are then stored in a magnetic storage device, preferably a magnetic disc. The signals from a single sonar pulse are stored in groups, equal in number to the number of receiving transducers, at nonadjacent locations on the disc track, and the signals corresponding to equal range elements from previous and subsequent pulses are stored at adjacent locations in the order received. The disc rotates 360* + OR phi during one picture interval to provide the moving picture display on a cathode ray tube electrically connected to a read head on the magnetic storage means.
