摘要： Docking sonar uses first and second fan-shaped beams sequentially scanning a target zone in mutually perpendicular directions. Target returns from one beam scan are compared with target returns from the other beam scan and the results are placed into a storage medium such as a video disc and then displayed on a conventional TV monitor, with brightness of the target on the display being an indication of target range.

摘要： 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.

摘要： The position of a carrier from a navigational reference generates X,Y coordinate navigation signals which are scaled as distance along a TV line of a TV display and a line number in the frame of the TV picture. A continual updated track of a moving vehicle is therefore displayed on a TV monitor, and if a video disc is used, can be recalled from the non-volatile memory for later replay.
