Abstract :
Estimating cross-range motion parameter is one of the most important steps while using antenna array to get targets´ 3-D ISAR images. A method which can estimate cross-range motion parameter based on DCFT is proposed in this paper. It can not only lower the amount of computation, but also insure the imaging precision. The validity of the method would be proved by simulation.
