| 摘 要： | 提出了一种新的干涉合成孔径雷达(InSAR)复图像配准算法,新算法使用干涉相位图的平均周期图作为配准的评价测度函数,采用数据分段求平均的方法降低了评价函数的估计方差,从而提高了配准的精度与可靠性。还分析了评价函数的估计偏差对配准的影响。最后使用平均周期图法进行了配准实验,试验结果验证了新算法在提高配准精度方面的有效性。

| Abstract: | A novel algorithm for InSAR SLC coregistration is proposed.The averaged periodogram is used as evaluation function of registration in the new algorithm and the estimation variance of evaluation function is reduced by separating the data into numbers of subsections and averaging them,thus the accuracy and reliability of registration is improved.The influence on registration of the evaluation bias is analyzed too.A registration experiment based on the averaged periodogram algorithm is carried out finally,whose result proves that the new algorithm could improve the accuracy of registration efficiently. |
