Abstract :
Recent developments in weather radar technology are discussed and results obtained with the NOAA/NSSL polarimetric Doppler research radar are shown. These include mitigation of range velocity ambiguities via systematic phase coding of transmitted signal and staggered PRT technique. Reduction of errors and faster volume scans is possible by decorrelation transformation (whitening) of oversampled signals in range. Spectral processing of polarimetric variables brings a new dimension whereby it is possible to adaptively recognize ground clutter and filter it as well as to estimated winds by separating passive wind tracers (such as insects) from migrating birds.
