Abstract
In this paper, a new digital processing algorithm based on the fast polynomial transform is developed for producing images from Synthetic Aperture Radar data, This algorithm enables the computation of the two-dimensional cyclic correlation of the raw echo data with the impulse response of a point target, thereby reducing distortions inherent in one-dimensional transforms. This SAR processing technique was evaluated on a generalpurpose computer and an actual Seasat SAR image was produced. However, regular production runs will require a dedicated facility. It is expected that such a new SAR processing algorithm could provide the basis for a real-time SAR correlator implementation in the Deep Space Network.
