A Method for End-To-End Blind Calibration of Z_DR in Polarimetric Weather Radars

In the absence of a standardized method for the calibration of polarimetric parameters, there is a general consensus to use several methods, with one of them being end-to-end, particularly for differential reflectivity. This article presents a new method for the calibration of differential reflectivity. It is a blind method, meaning that it does not require knowledge of the characteristics of the observed target during calibration, and it is end-to-end. This method is based on the consistency of two estimators of the second -order moments of the voltages received by a polarimetric radar for different parameters at transmission.
