5b.6 Optimum Processing in Range to Improve Estimates of Doppler and Polarimetric Variables on Weather Radars

Radar meteorology applications rely on pulsed weather radars that survey the atmosphere and estimate a set of meteorological variables for each resolution volume. The reliability of these applications depends on the quality of the supplied data. To reduce the statistical uncertainty of estimates of spectral moments and polarimetric variables for each resolution volume, weather radars often average signals from many pulses. Therefore, the variance reduction of averaged estimates is inversely proportional to the equivalent number of independent samples MI. This number is given by
