Experimental validation of the interferometric coherence formulation in single-transmit mode

The use of polarimetric interferometry to monitor vegetation covers, assuming simple models like the RVoG, is influenced by the acquisition mode of the interferometer: single-tx or alternate-tx. Theoretical expressions obtained for the single-tx mode have not been validated with real data yet. In this work we address this validation by employing a new laboratory SAR system and by analyzing TanDEM-X data.
