Preliminary Process of Airborne Multidimensional Space Joint-observation SAR System

With the development of Synthetic Aperture Radar (SAR) technology, Multidimensional Space Joint observation, which includes polarimetry, frequency, angle, and time spaces, has become an important trend in SAR development, but there are few reports on systems and experiments about it. In this paper, the capabilities of the airborne Multidimensional Space Joint-observation SAR(MSJosSAR)system are briefly described and the technical characteristics of the system are summarized. A SAR consistently imaging algorithm is proposed and the registration accuracy of Multiband image is better than 1 pixel. The preliminary process of three multidimensional space joint-observations, including multi-band polarization angle feature quantity, multi-aspect tomography three-dimensional reconstruction, are analyzed, multitemporal coherence change detection, which verify the ability of multidimensional space joint-observation.
