Pauli Phase Calibration in Compact Polarimetry.

In this paper, we consider the problem of true transmitter polarization state estimation for circular compact SAR modes. We employ two methods-the first using point targets such as trihedral reflectors, and the second, a new method, based on the Pauli phase observed over distributed targets like forest canopy. We first show how compact modes allow estimation of the Pauli phase for reflection symme...
