Wideband Pol-Sar/isar Signal and Image Processing for Target Identification and Discrimination

Abstract

Following a summary of the basic principles of polarimetric SAR and ISAR, a special decomposition is mentioned in some detail, and the superior capability of polarimetric radars compared with traditional single polarization radars is pointed out by applying the decomposition to simulated images of a composed model target, and to measured POL-SAR data. INTRODUcIlON To completely characterize the reflectivity of a radar target, the vector nature of the elmmagnetic wave has to be taken into account. This is done by specifying the field vector and its interaction with the target in an orthogonal basis, typically a linear basis with horizontal and vertical components related to the antenna orientation, in other words the antenna polarization.
