Polarimetric weather radar base moment algorithm validation

Polarimetric weather radars measure very small differences in received signals between channels. Thus, the calibration of the systems must be very precise and the algorithms used to generate the base moment data must minimize error. In order to assess the system calibration and validate the base moment algorithms, a series of procedures were developed using commercial waveform generator equipment and common RF and IF componentry. This paper describes the validation procedures and results.
