Abstract

Fourier analysis based focusing of synthetic aperture radar (SAR) data collected during circular flight path is a recent advancement in SAR signal processing. Fast CSAR algorithm uses the Householder transform to obtain a ground plane circular SAR (CSAR) signal phase history from the slant plane CSAR phase history by inverting the linear shift-varying system model, thereby circumventing the need for explicitly computing a pseudo-inverse. The Householder transform has recently been shown to have improved error bounds and stability as an underdetermined and ill-conditioned system solver, and the Householder transform is computationally efficient.
