This paper introduces a method to include focusing of ground movers within a framework of fast factorized SAR backprojection which enables long coherent integration times. Also, sensitivity and resolvability of ground mover motions are improved with longer integration time. Branching off velocity and acceleration channels in a controlled manner in fast factorized backprojection, the processing burden is minimized.
