  • 摘要: 该文研究基于频分正交信号的机载交轨稀疏阵列SAR下视3维成像问题。为解决孔径综合方法带来的重复频率高、数据冗余量大和运动补偿等问题,提出一种基于修正均匀冗余阵列(Modified Uniformly Redundant Arrays, MURA)编码和干涉处理频域稀疏的3维成像方法,直接在距离频域稀疏采样条件下对目标场景进行下视3维成像。引入MURA编码对回波数据在阵列采样平面进行正反编码调制,分别获得两幅3维复图像,并通过干涉处理使信号3维频谱集中在低频段,利用频域低通滤波或压缩感知(Compressed Sensing,CS)实现目标场景3维成像。该方法具有回波数据利用率高和工作重复频率低的特点。仿真分析和试验数据验证了方法的有效性。
