The Evaluation of Two Rank-Order Quantizers as Modifications to the Common Digitizer.

Abstract

Two rank-order quantizers (ROQ's) were installed in the common digitizer (CD) located at the Elwood, New Jersey, National Aviation Facilities Experimental Center long range radar. Both ROQ's were designed to operate with a radar-transmitted pulse of 2 microseconds. Tests were conducted on the ROQ's and the Improved Quantizers to determine their performance with respect to one another. Test results indicated equivalent reduction in automatic clutter eliminator (ACE) total blank areas when comparing two ROQ's with the Improved Quantizer. Also, it was concluded that an ROQ employing a guard band around the target tap performed virtually the same as the Improved Quantizer in detecting search targets. The ROQ employing no guard band around the target tap resulted in a reduction in search target detection. It is recommended for future CD procurement that the ROQ be considered as a replacement for the Improved Quantizer because of its design simplicity and reliability. (Author)
