Change analysis and interpretation in polarimetric time series over agricultural fields at C-band

Abstract

This work introduces a polarimetric SAR methodology for the detection and interpretation of changes occurring between polarimetric SAR acquisitions. The proposed methodology is able to describe not only the amount of change, but also the type of change. The technique is evaluated with a real C-band SAR dataset over agricultural areas, supported by an extensive set of ground measurements available to assess the detected changes. These measurements in conjunction with SAR tomography will be employed in order to determine their correspondence with the physical changes in agricultural crops.
