摘要：
In this Paper a refined chirp scaling algorithm for spaceborne synthetic aperture radar(SAR) imaging is presented At first, the model of spaceborne SAR is analyzed Based on the squint range model a refined chirp scaling algorithm is derived And it is suitable for precise imaging of high resolution spaceborne SAR with large range cell migration. Based on the refined chirp scaling algorithm the system architecture is presented.
