ASR-8/TDX-2000 Performance Analysis: Evaluation of Multiple-Time-Around-Detection (MTAD) Algorithm and Final Report

This report documents the analysis of and subsequent improvements to the performance of the ASR-8/TDX-2000 digitizer equipment combination. Working at the Federal Aviation Administration's (FAA's) Palm Springs, CA and Williams (Mesa, AZ) ASR-8 facilities, data were methodically collected and analyzed to isolate the causes of reported correlated radar-only tracks that were being dropped or were never initiated. These problems were subsequently fixed via hard and soft parameter changes in the TDX-2000. A significant study was also undertaken in conjunction with the Sensis Corporation to improve the TDX-2000's capability to reject returns from multiple-time-around detections. The details of that algorithm modification and the results of follow-on testing and analysis are described. Final conclusions on the status of the project are also included.
