Test and Evaluation of the Radar Processing Subsystems of the All Digital Tracking Level System.
Abstract
This report contains the results of tests that were conducted to determine the performance of the radar processing subsystem of the All Digital Tracking Level System. The measure of the performance was based primarily on target detection sensitivity, false target rates in clutter and clutter-free environments, clutter mapping, and quantizer regulation. The tests consisted of bench tests and tests employing weather clutter samples. Input videos were derived from both an ASR-5 and ASR-7 radar radiating from the National Aviation Facilities Experimental Center (NAFEC) Terminal Facility for Automation and Surveillance Testing (TFAST). It was concluded that the rank-order quantizer delivered by the contractor did not perform to theoretical expectations. However, the model designed and fabricated by NAFEC was successful in achieving expected results. The second-threshold control function regulated false targets in weather clutter environments to a half order of magnitude of a .00001 rate. Target detection sensitivity was acceptable, but could be improved by utilizing a hardware detector that does not employ a predetector function. Finally, the video select mapping function requires improvement in performance. (Author)
