Degree of Polarization at Simultaneous Transmit: Theoretical Aspects

Abstract

We consider weather radar measurements at simultaneous transmission and simultaneous reception of horizontal and vertical polarizations and show that the degree of polarization at simultaneous transmit (ps) is related to differential reflectivity and copolar correlation coefficient at simultaneous transmit (namely, ZDRs and ρhys). We evaluate the potential of degree of polarization at simultaneous transmit for weather radar applications. Ultimately, we explore the consequences of adjusting the transmit polarization state of dual-polarization weather radars to circular polarization.
