An underwater floodlit scene is viewed by a TV camera. The first few active TV lines in the scan format, indicative of the illuminated field where backscatter is a minimum, are stored on a video disk. As the apparatus travels over a target area to be viewed, subsequent portions of the TV video signal from the minimum backscatter area are subsequently stored on the disk. The stored signals are then displayed on a TV monitor as a moving window display. The number of active TV lines gated for storage on the disk may be made proportional to the carrier vehicle speed, altitude and camera viewing angle, or field of view.
