dc.description.abstractThis paper summarises how SAR data collection can be viewed as taking the Circular Radon Transform of the ground reflectivity and outlines how image formation can be achieved by inverting the CRT via a Fourier-Hankel transform. An expression for the point spread function (PSF) of the imaging process is arrived at by means of an analytic inversion for a Gaussian. This PSF shows the effect on the image of the finite synthetic aperture. Illustrations of the PSF to show its range and aperture dependence are given.en
