摘　　要：对近场扫描架三维SAR成像原理及处理技术进行了详细研究,该技术能够修正近场成像测量中天线方向图及距离因子等引入的误差,在近场测试区域内获取目标散射中心真实的三维散射强度分布图,仿真和实测成像数据均验证了该方法的正确性和可行性。This paper presents the theory and imaging algorithm of 3 -D imaging based on scanner.The technology can acquire the distribution of target's scattering intensity in near-field by eliminating the error of the Antenna pattern and range factor,and both simulating and measurement data prove its validity and feasibility.
