Antiparallel Aspects of Airborne Dual-antenna InSAR Data Processing and Analysis

  • 摘要: 干涉合成孔径雷达(InSAR)技术具有高精度的地形测绘能力。然而在山区地形条件下,受SAR侧视成像的影响,存在较多的几何畸变区域,干涉相位表现为不连续或者缺少有效信息的情况,对单一的干涉图像对处理难以得到精确的数字高程模型(DEM)。融合两个或多角度的干涉数据可以用于解决这一问题。该文根据这一思路利用机载双天线InSAR对飞数据进行实验,针对山区地形条件下参考高程近似影响运动补偿精度的问题提出了基于高程迭代的运动补偿方法,对于阴影、叠掩区域容易导致相位解缠误差的问题提出基于地形特征的相位解缠方法,从而尽可能降低单一角度数据的DEM误差,以达到消除对飞数据重叠区域3维定位不一致的目的,拼接实验结果验证了处理方法的有效性。
