A Comparative Study of the Polar Version with the Subimage Version of Fast Factorized Backprojection in UWB SAR
Responsible organisation
2008 (English)Conference paper, (Refereed) Published
Abstract [en]

This paper presents a comparative study of the polar and the subimage based variants of the time domain SAR algorithm Fast Factorized Backprojection. The difference between the two variants with regard to the phase error, which causes defocusing in the image, is investigated. The difference between the algorithms in interpolation between stages is also discussed. To investigate the sidelobes in azimuth, the paper gives simulation results for a low frequency UWB SAR system for both algorithms. How the algorithms differ with regard to amount of beams and length of beams is also discussed.
