Apparatus which automatically detects targets of interest in line scanned amplitude modulated data systems such as side scan radar or sonar. The apparatus examines a received signal for target highlights followed by a target shadow of a certain length, depending upon range. The apparatus indicates the presence of a target of interest when the highlight-shadow information is contained in multiple sequential signals over a predetermined range window.

Automatic target detector

The beam signals of a multibeam sidelooking sonar system are initially time compressed in a first, relatively low speed, logic section and thereafter transferred to a relatively higher speed logic section for placement onto a video disc. The signals from the video disc are presented to a TV display with the information being portrayed as a moving window. The scan conversion operation may be modified to provide a substantially correct picture geometric format as the vehicle carrying the sidelooking sonar apparatus varies its velocity.
