| 摘 要： | 提出一种利用条带间连接点进行多条带干涉定标的方法.该方法利用条带间重叠区的连接点作为控制点,既实现了多条带数据的干涉定标,又有效减少了地面控制点数量.实验结果表明,该方法可以准确获取各条带的干涉定标参数,并能解决实际应用中大量布设地面控制点的问题,降低了外定标工作的困难. |
| 关 键 词： | 干涉合成孔径雷达 干涉参数定标 敏感度方程 连接点 辅助地面控制点 |

| Abstract: | Calibration of multi-strip airborne InSAR data is needed in order to generate DEMs over large areas.We propose an interferometric calibration method for multi-strip InSAR data.The method can reduce the GCP number using connected points in the overlap area between strips and is shown to be effective by the experimental simulation.The results indicate that the interferometric parameter error of each strip can be calibrated accurately with a reduced number of GCP which could reduce the difficulty of InSAR outer calibration. |
