Spaceborne Video SAR imaging mode is a new imaging mode of SAR (Synthetic Aperture Radar), it is different from the traditional imaging mode. Operating in this mode, SAR provides continuous surveillance over a region of interest. Sequence images are processed afterwards and the information of the region is reappeared using video formed by sequence images. Obviously, this will bring many advantages for detecting and tracking moving-targets over the region of interest. Therefore, in this paper, the concept of spaceborne Video SAR is introduced at first, then the performances of spaceborne Video SAR, such as data process methodology, resolution and frame rate are discussed. Based on the above analysis, a modified Deramp Chirp Scaling (DCS) algorithm with an extra phase compensation factor is proposed to deal with spaceborne Video SAR data.
