New possibilities of the use of synthetic aperture millimeter-wave radiometric interferometer for precipitation remote sensing from space

The study of precipitation using the observation of the Earth from space is one of the important problems of remote sensing [1]. In the previous studies, the polarization of precipitation radiation was not taken into account, which is represented by second Stokes vector component Q. Polarization effect of rain radiation caused by the flattening of large rain drops during their fall to the Earth is a typical signature of precipitation [2]. As it is known, the Stokes vector expressed in a horizontal-vertical linear polarization basis (h,v-basis) is build from the electrical field components E_h and E_v. The Stokes vector components have the dimension of intensity.
