| Abstract | This report presents the results of a study performed by the Transportation Systems Center (TSC) to evaluate two proposed enhancements to the performance of the ASDE-3 Radar in heavy rain: Adaptive gain and adaptive clutter thresholding, (operating with frequency agility). The study was based on analysis of radar and rate of rainfall data collected by TSC during the ASDE-3 Engineering Tests and performance predicted by the ASDE-3 System Performance Model. Both enhancements were found to be subject to errors due to non-uniformity of rain. Adaptive gain was found to be fail-soft and of net benefit to ASDE-3 performance whereas adaptive clutter threshold which is subject to error from variations in both clutter and attenuation was found not to be of benefit. Information to aid in design and installation of an adaptive gain subsystem and alternative approaches for less demanding airports are also presented. |
