Hard-in-loop Polarization Linear SAR Imaging System
A hard-in-loop polarization Synthetic Aperture Radar (SAR) system was constructed in an anechoic chamber. The operation track of SAR was simulated by lateral movement of a scanner. As the core hardware of system,a vector network analyzer was set in the scanner and moved together. Two measured channels were connected with four vertical or horizontal antennas by the expand ports. Then the full-polarization scattering matrixes were collected with the scanner moving. An improved back-projection algorithm was adapted to process the echoes,and four different polarization images were gained. The experiments were carried out on L-band. The measured scene consisted of three fir trees. The images are coincident with the physical characteristic of scene.
