Truck characteristic analysis from all aspect angles with quad-pol Radarsat-2 SAR images

In order to expand SAR application into vehicles monitoring, it is necessary to analysis and model the vehicle´s characteristics under different SAR imaging conditions. In this paper, three typical trucks at different aspect angles were imaged by Radarsat-2 quad-polarimetric SAR image with different incidence angles in the field. RCS measurement and polarimetric decomposition were used to analysis the variation of vehicles phenomenon in SAR image. Some benefited conclusions are drawn based on analysis of the curve of RCS and polarization component which are varying with the aspect angle, incidence angle and structure.
