摘要
回顾了机载合成孔径雷达数字信号处理的基本算法及其特点 ,选用了支持多种模式、适合 DSP处理的 Chirp Scaling算法。提出并设计了基于此算法的多处理机并行工作的 SAR处理机硬件体系结构。分析了此体系结构采用串行流水的合理性 ,介绍了各处理机的特点 。
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.
