Estimation of the Phase Shift Between Simultaneously Transmitted H and V in the SHV Mode

A method for measuring the phase shift between the horizontal and vertical polarizations, simultaneously transmitted by weather radars using the SHV method for polarimetric measurements, is presented. The method is based on the 3-PolD method and requires the antenna to be azimuthally rotated when pointing to the zenith as for $Z_{dr}$ calibration.
