Spectral moment estimation of weather echoes in pulsed Doppler weather radars: Spectrum width
We define and compare the statistical characteristics of the estimates of Doppler velocity spectrum (DVS) width of meteorological formations (MF) based on the various modifications of “pulse pair” method. For the conditions, when the form of unimodal DVS differs from the Gaussian one, the errors of proposed modification of “pulse pair” method are evaluated, and possible ways to reduce them are proposed. The recurrent organization of estimation procedure that minimizes the computational costs is proved.
