摘要

摘要: 圆迹合成孔径雷达（CSAR）的360全方位观测能够获取目标各方向的散射特征，但是单轨迹圆迹SAR对于强方向性目标高度向散射特征的获取能力非常弱。该文针对典型目标开展3维圆迹SAR干涉方法研究，开展了基于暗室实验的原理性验证，首次给出了实际坦克金属模型的干涉圆迹SAR的3维重建结果，验证了该方法的有效性，同时展示了3维重建与全方位观测相结合在目标精细特征描述方面具有的重要应用潜力。

Abstract: Circular Synthetic Aperture Radar (CSAR) can acquire targets' scattering information in all directions by a 360 observation, but a single-track CSAR cannot efficiently obtain height scattering information for a strong directive scatter. In this study, we examine the typical target of the three-dimensional circular SAR interferometry theoryand validate the theory in a darkroom experiment. We present a 3D reconstruction of the actual tank metal model of interferometric CSAR for the first time, verify the validity of the method, and demonstrate the important potential applications of combining 3D reconstruction with omnidirectional observation.
