摘　　要：针对高分辨率星载SAR成像处理流程的特点,提出一种高分辨率星载SAR并行成像处理系统方案。该系 统能完成星载SAR数据预处理、轨道参数及多普勒参数计算、多普勒参数估计、成像处理以及辐射校正等功能。系统采 用模块设计,具有很强的向后兼容和可扩展性;同时,基于多CPU高性能计算机的并行结构,使系统具有很高的实时性。 测试证明系统设计合理和有效。In this paper,the design of a high resolution Spaceborne SAR data processing system is presented. This data processing system contains a series of functions,such as data preprocessing, the calculation of orbit parameters, the calculation and estimation of Doppler parameters, image processing,radiation calibration moduling,and so on. This system is of strong backward compatibility and extensibility as well as high real time processing capability due to the parallel and modular desigh. The feasibility and effectiveness are validated by Computer simulation.
