Abstract

Polarimetric phased-array radar (PPAR) creates biases in observed polarimetric parameters when the beam is pointed off broadside. Thus, a bias correction matrix needs to be applied for each beam direction. A bias correction matrix is developed for array elements consisting of either waveguide apertures or patches. Correction matrices are given for both the Alternate Transmission and Simultaneous Reception mode and the Simultaneous Transmission and Simultaneous Reception mode. The biases of polarimetric parameters measured with a PPAR without the application of a correction matrix are presented.
