A new method of three dimensional synthesis aperture radar（SAR） imaging is proposed,which is realized by combining the scanning methods of the planar scanning and wideband sweeping.The technology can get the real three dimensional scatting-center distribution of targets in near field by correctting the effects of antenna pattern and distance factor in near field measurement,and the results of measuring and simulation of the proposed method match very well which validate the correctness and feasibility of the technology.
