摘要: 该文提出一种基于单演信号理论的SAR图像配准的新算法。利用单演信号局部特征构造一个单演相位一致函数，用来检测SAR图像特征。利用单演信号分量构造单演向量，通过求单演向量相关，解决SAR图像特征点的匹配问题。实验结果显示，算法能较好完成SAR图像自动配准。Abstract: A new algorithm is proposed for SAR image registration based on monogenic signal theory. A monogenic phase congruency function is constructed using the characteristics to detect feature points in SAR image. On the other hand, a monogenic vector is composed by the 3-triple components to solve the problem of feature points matching in reference SAR image and sensed SAR image. Diverse SAR image data are used for verification and the experiment results indicate that the proposed algorithm has a good performance of SAR image registration.
