NEXRAD data quality by spectral processing. Spectral processing on NCAR's S-Pol radar

The WSR-88D radar system (NEXRAD) is developing a phase coded pulsing scheme using spectral processing that will improve data quality by removing overlaid echo contamination. A prototype spectral processor has been implemented on NCAR's S-Pol research radar for validation testing. Spectral processing will simultaneously enhance the anomalous propagation clutter mitigation technique, which uses a fuzzy logic based radar echo classifier, and allow future data quality enhancements.
