摘要

摘要: 高分辨率机载干涉合成孔径雷达(Interferometric Synthetic Aperture Radar, InSAR)是获取高精度数字高程模型(Digital Elevation Model, DEM)的重要手段之一。由于主副天线距离向相位方向图存在差异等原因，导致干涉相位偏差沿距离向变化，而传统的干涉定标方法将干涉相位偏差视为常数进行定标，无法消除干涉相位沿距离向变化的误差，因此使得定标后反演得到的高程存在距离向空变误差。针对该问题，该文提出一种单独将干涉相位偏差沿视角进行多项式拟合的定标方法。最后，利用一组机载实测数据对该方法加以验证，实验结果表明，该方法能有效地解决高分辨率机载InSAR高程测量距离向误差的空变问题。

Abstract: High resolution airborne Interferometric Synthetic Aperture Radar (InSAR) is one of the important methods to generate high precision Digital Elevation Model (DEM). Due to the phase pattern difference between the two antennas, the interferometric phase bias varies with the range. The traditional interferometric calibration regards the phase bias as a constant, and it is not able to correct the range-variant phase errors. Therefore, there are range-variant errors of the reconstructed elevation. To solve this problem, this paper presents a calibration method that uses polynomial to fit the interference phase bias. At last, a set of real airborne InSAR data are used to validate the method, and the experimental results show that the proposed method can solve the problem of range-variant height errors in high resolution airborne InSAR effectively.
