Review of Inverse Synthetic Aperture Radar (ISAR), Polarimetric ISAR Imaging and Interpretation

In this work, a brief but a complete review of Inverse Synthetic Aperture Radar (ISAR) imaging theory is given and the usage of polarimetric imaging concepts in ISAR imaging is shared. First, a very quick summary of ISAR imaging concept is revisited to highlight the key parameters of ISAR imaging such as the geometry, the formulation and the resolution metrics. Then, an example of two-dimensional ISAR image is shared. In the second part of the paper, one of the most comprehensive research topics of ISAR imaging that is polarimetric ISAR is being covered. First, the aspects of polarimetric data collection are revisited. Then, Pauli decomposition technique and its usage in ISAR images are explained. Then, an example of polarimetric ISAR image is provided to together with the polarimetric interpretation of the resultant image.
