摘要：

The velocity SAR (VSAR) is conceptual radar imaging system capable reconstructing the three-dimensional range/azimuth/velocity image for a scene that contains moving objects. It combines the high resolution imaging capability of SAR with the clutter rejection capability of MTI systems. The clutter rejection and motion estimation capabilities of VSAR make it potentially useful for a variety of missions. The system concept is described, the basic signal-processing algorithms are developed, and a performance analysis of the VSAR system in the context of detecting low-RCS ground targets is provided. The VSAR system is able to estimate the speed of moving targets, down to slow speeds of the order of 0.5 m/s.
