Study Of Microwave Imaging Algorithm

This thesis, based on the ISAR, introduces the algorithms of microwave imaging. The paper discusses three imaging methods, namely Range-Doppler Imaging, polar-format processing, tomographic formulation. The Rang-Doppler imaging forms imagery through one dimension Fourier-transformed twice in Cartesian coordinate. Polar-format processing use the data in polar format, which can obtain clear imagery at the larger rotating angle. Tomography involves the reconstruction of images from projections of object's spatial distribution, which are obtained at regular increment of viewing angle. We obtain the point-spread function(PSF) and the imageries through calculating. The last question we discuss is the construction of ISAR system.
