Evaluation of Improved Quantizer Detector Modification to the Production Common Digitizer

摘要

A quantizer detector modification was installed in the Production Common Digitizer AN/FYQ-47 located at the Elwood, New Jersey, National Aviation Facility Experimental Center long-range radar site. The purpose of the modification was to improve the search target detection capabilities of the digitizer, particularly in radar clutter environments. This was accomplished by providing adaptive feedback loops in the quantizer and improving the Automatic Clutter Eliminator (ACE) logic circuitry. A series of element and subsystem tests were conducted to compile data for use in comparing the operational performance of the digitizer with and without the improved circuits.
