ANGEL CLUTTER AND THE ASR AIR TRAFFIC CONTROL RADAR. VOLUME I. STUDY RESULTS

The goal of this study was to identify angel clutter reduction techniques which were cost-effective for the existing ASR-4, 5, and 6 radars. This report identifies a combination of techniques which can be implemented without major radar re-design and which improves the ASR surveillance capability. These techniques were developed by through analysis of ASR video and track radar data gathered during the Spring 1972 bird migrations at Milwaukee's General Mitchell Airport. The proposed angel clutter reduction (ACR) features operate on the three major differences observed between angel and aircraft signal characteristics: signal strength, pulse-to-pulse amplitude fluctuations, and velocity. These ACR features were chosen becausethey provide the highest level of effectiveness consistent with timely implementation and a reasonable degree of radar modification. (Modified author abstract)
