Assessing Reciprocity in Polarimetric SAR Data
IEEE Geoscience and Remote Sensing Letters, 2020 This letter studies the conformity with the reciprocity theorem on the measured polarimetric synthetic aperture radar (SAR) data. The problem is formalized via a binary hypothesis test where the reciprocity assumption is tested versus its alternative (absence of reciprocity).
