Abstract

Abstract:

The Chirp Scaling algorithm and its characteristics used in the airborne Synthetic Aperture Radar are reviewed. Mapping the algorithms structure into the hardware of a real time processor system, the authors have designed and implemented the architecture of the SAR real time processing system. The paper briefly introduced the architecture and components of the system, and stressed the communicating methods based on Control Bus and Dedicated Data Channel between the components of the system.

Key words: synthet ic aperture radar, DSP, mult ip rocesso r, arch itecture
