| 摘 要： | 与传统的直线SAR相比，圆周SAR(CSAR)具有对场景进行3维成像的能力。该文提出了一种基于波前重构的圆周SAR 3维成像的新方法，该算法通过补偿掉雷达运动轨迹引入的相位项的方法实现了图像的聚焦，避免了Hankel函数的计算，从而大大降低了算法实现的复杂度。仿真与实测CSAR数据成像结果验证了该算法的有效性。

| Abstract: | The Circular Synthetic Aperture Radar(CSAR),unlike the linear SAR,has the capability to extract three-dimensional imaging information of a target scene.In this paper,a novel CSAR wavefront reconstruction method is proposed for three-dimensional imaging.The proposed method compensates the effects of the phase components introduced by the radar’s trajectory to form reconstructed image,which avoids calculating the complicated Hankel function.Thus the complexity of the algorithm can be reduced.Finally,the validity of the presented method is clarified by both simulated data and experimental data sets. |
