C-band polarimetric SAR measurements for the monitoring of growth stages of corn fields in the piana DEL Sele zone

C-band RADARSAT-2 quad-Poland X-band COSMO-SkyMed incoherent dual-polarization PingPong SAR data are used to monitor corn fields phenology. The polarimetric analysis carried out at C-band shows a sensitivity of polarimetric observables to corn phenology that allows to interpret the different polarimetric signatures occurring along the cultivation cycle. Unfortunately, at the X-band, a physical interpretation is not properly provided, due to the unavailability of radar acquisitions for the most of the cultivation cycle. This is due to defense requirements which caused conflict acquisitions with the planned COSMO-SkyMed SAR data.
