Optimised image autofocusing for polarimetric ISAR

The use of full polarisation enables multi-channel SAR processing for enhancing both imaging and classification capabilities. In the field of Inverse Synthetic Aperture Radar (ISAR) very little has been investigated, especially from the point of view of multi-channel ISAR image formation. In this paper, the authors want to define an optimised image autofocusing technique that exploits full polarisation information. Theory and simulation results will be provided in the paper.
