<p>A system for automatically processing quantized normal and MTI radar video to provide improved clutter rejection and improved detection of moving targets in clutter. The quantized MTI video is applied to a mean level detector, which has its sensitivity controlled as a function of the number of detected target reports being stored in an output buffer unit in order to automatically provide the proper threshold to prevent a data link from being saturated by clutter targets. The quantized MTI video output of the mean level detector and the quantized normal video are applied to a video selector circuit, which is controlled by a clutter pattern sensor for each range bin interval of a radar sweep to automatically select for subsequent detection and processing the MTI video in all range bin intervals having clutter and the normal video in all range bin intervals not having clutter.</p> |
