摘要

The image formation process of a high-resolution space-borne synthetic aperture radar is a demanding task with high computation and precision requirement. When it is implemented on a restricted onboard real-time DSP processing system, the algorithm and software optimizations are essential to the success of the implementation. We implemented the capability of real-time processing for the raw data of a type of high-resolution space-borne SAR on an onboard DSP processing system. The refined Chirp Scaling algorithm is parallelized and mapped into the system. Approaches have been presented to improve the computation speed and precision, based on academic and mathematic analysis. Additionally, the formula of the refined Chirp Scaling is re-deduced, and the system is tested and verified by the simulated space-borne SAR and Radarsat-I raw data.
