Effects of filtering on estimating spectral moments of meteorological Doppler spectra

The authors describe the effort to develop a means of evaluating a clutter-rejection filter based on how it effects the pulse-pair processor spectral estimates of weather data in the absence of clutter. Several clutter-rejection filters are evaluated and compared with a baseline ideal filter. The loss of sensitivity, a measure of the signal power lost as a result of filtering, is also considered in the analysis. The results presented have been obtained from simulated weather data at very high signal-to-noise ratios in the absence of ground clutter. Little of the analysis software´s capabilities has been explored
