Polarimetric Hot Spot Processing for ISAR Image Autofocusing

In recent studies the possibility of extending autofocusing techniques to fully polarimetric ISAR systems has been proposed. One of the first techniques for ISAR image autofocusing still in use is the Hot Spot processing. In this paper, the Hot Spot technique is extended and applied to fully polarimetric ISAR data. A performance analysis is then provided and compared to single polarisation Hot Spot by using real data.
