Abstract : The report contains the results of tests that were conducted to determine the performance of a radar quantizer having distribution-free characteristics as compared to that of an existing type of quantizer employing mean level techniques. Several types of range binners were developed and tests were performed to ascertain the false target rate and detection capabilities of each of the quantizer and range binner configurations. The tests consisted of both bench tests and those employing weather clutter samples from the National Aviation Facilities Experimental Center (NAFEC) ASR-5 environment. Additionally, performance of the radar processor with inputs derived from a moving target indicator (MTI) video, that was designed to have an extended dynamic range, was investigated. It was concluded that the design of the rank order quantizer described in this document approaches theoretical performance. Detection loss is experienced at range cell boundaries. The extended range MTI provides comparable performance to that of MTI log but is far less costly. Additionally, second threshold control is capable of maintaining a false target rate acceptable as an input to a tracking algorithm.
