摘要 从阵列天线合成孔径雷达(SAR)的信号模型出发,提出了一种基于俯仰角压缩的阵列天线SAR三维成像算法,解决了阵列天线SAR中存在的距离单元徙动项的校正问题,从俯仰角压缩的角度分析了阵列天线SAR的三维成像原理.通过计算机仿真验证了信号模型和三维成像算法的有效性. Based on the signal model of SAR with linear array antennas,a three-dimensional imaging algorithm using elevation angle compression principle is proposed.Range cell migration correction （RCMC） is incorporated in the three-dimensional imaging algorithm.The three-dimensional imaging principle of SAR with linear array antennas is analyzed from the point of view of elevation angle compression principle.The simulation results support the signal model and three-dimensional imaging algorithm.
