Abstract:

The Radar Processing Subsystem RPS of the All-Digital Tracking Level System was employed to conduct comparative testing of an analog and a digital rank-order quantizer ROQ. The analog unit was that designed by National Aviation Facilities Experimental Center NAFEC to replace an inferior version supplied under contract. The digital ROQ employed an eight-bit analog-to-digital converter and was furnished by the ARTS 3 contractor. The tests were performed for several system configurations, including two modifications to the digital ROQ. Performance characteristics were based on percent noise regulation, target detection sensitivity, false target rates, isolated-hit stability, target hit distribution, and video select mapping, as achieved with the RPS. It was concluded that the digital ROQ produced equal to or better system performance, as compared to the analog ROQ provided that the automatic gain control and 5050 modifications to the digital ROQ were employed.
