Paper Abstract

A highly regular and computationally efficient SAR image formation processor architecture has been developed for wide-area ground surveillance systems. The architecture is based on the repetitive use of a very simple small FFT kernel (instead of a large 2D FFT) providing a variable resolution capability. The first stage of the planar subarray processor (PSAP) forms coarse images and constructs polar formatted, pseudo spotlight SARs. The second stage evaluates the requisite 2D transforms in a multiple- stage block FFT, providing variable resolution images. The fold- FFT is paramount to the computational efficiency of the approach.
