Agricultural monitoring with polarimetric SAR time series

This paper describes the monitoring of agricultural crops and their evolution with Polarimetric Synthetic Aperture Radar (PolSAR) time series. SAR polarimetry is very useful for this task due to its sensitivity to the plant structure. A polarimetric change analysis is proposed in order to detect and characterize the observed differences between two acquisitions. This analysis is able to determine the types of scattering that increase or decrease among acquisitions, which allows a better interpretation of the change. Then, the proposed technique is evaluated with the AgriSAR 2006 dataset in order to verify the results and compare them with the ground measurements.
