ABSTRACT:
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.
