<p>PURPOSE: To provide a video signal main processing device which properly removes different sorts of clutters and noises distributed in the signals received by a radar, and thereby heightening the ability of detecting or capturing the target. CONSTITUTION: A main processing device for video signals is composed of a digitizer means 40, a CFAR processing means 50 to sense a pure target signal from video signals by the feedback integration and critical decoding, and a buffer and pixel timing control means 60 to put the video date in synchronization with the pixel. Thereby the clutter and noise level included in the radar video signals is reduced properly, and the target signal can be sensed while the FAR is kept constant, which should lead to enhancement of the target detecting and tracking ability of the radar system concerned.</p> |
