| 摘 要： | 基于单天线高分辨率机载SAR,研究了运动舰船目标三维形状重构问题。对运动舰船目标回波信号利用KEYSTONE变换和高阶相位拟合法完成距离徙动校正后,利用时频分析方法产生运动舰船目标二维图像序列,尝试着将因子分解法引入到SAR运动目标图像处理领域,通过因子分解法对二维图像序列进行处理,实现运动目标三维形状重构,最后给出了真实SAR数据的运动舰船目标三维重构结果,实验结果表明了该方法的有效性。

| Abstract: | The single antenna SAR moving ship targets 3D reconstruction is investigated based on high resolution airborne SAR. The range migration correction is completed by KEYSTONE transform and phase polynomial compensation. Time-frequency analysis imaging method can give a sequence of 2D ship images. Then, we introduce the factorization method to SAR image processing field. From these 2D images sequences, the 3D shape of ship targets can be reconstructed by factorization method. The imaging results of real SAR data show the effectiveness of this method. |
