摘要：
Transmit wave polarization (i.e., ellipticity and roll) deviation from the ideal or intended transmit mode affects compact polarimetry (CP) products and associated data exploitation. Hence, it is important to evaluate such effects on the CP model and account for the associated variations through data exploitations. This letter explores an approach to model and estimate ellipticity variations for calibration by taking advantage of a variational model and adjoint polarimetric synthetic aperture radar data.
