Application of fast back-projection techniques for some inverse problems of synthetic aperture radar

摘要

Abstract: In certain radar imaging applications one encountersthe problem of reconstructing a reflectivity functionfrom information about its averages over circles withcenter on a straight line. A robust inversion method isa filtered backprojection method, similar to the oneused in medical tomography. We will present a fastalgorithm for this backprojection operator. Numericalexamples are given.!6
