In this paper, a multi-temporal supervised binary-tree classification scheme (MTSBTCS-MDPS) is developed integrating the time dimension and the maximum difference of polarization signature (MDPS), in which each pair of targets is maximally distinguished through choosing the optimum orientation and ellipticity angles on an optimum data acquisition date. Seven C-band fully polarimetric RADARSAT-2 data with FQ21 mode acquired in 2012 over South-western Ontario, Canada are used for validation. Compared its classification result with that obtained from the single image by MDPS alone, the MTSBTCS-MDPS has much higher accuracy with its κ coefficient approximately 0.8 and overall accuracy of 84%.
