Abstract

This paper describes a new approach for ScanSAR data image generation, which performs efficient data processing and multilook operation without the need of interpolation stages. This new technique is based on the spectral analysis method (SPECAN) combined with the well-known chirp Z-transform. In this paper, it is also shown that this new method is very efficient for obtaining near real-time images for browsing or on-board burst mode image generation overcoming classical problems of the standard SPECAN method
