摘要 针对SAR处理中图像失配导致相应像素对的相干信息丢失问题进行研究,利用统计估计思想融合相邻像素相干信息,不仅利用当前处理像素,还利用其周围像素的复数据来构造像素数据检测矩阵,通过均方根偏差最小作为图像配准测度,提出一种稳健的多通道SAR自适应图像配准方法,该方法有效地增强了图像配准稳健性,同时提高了算法的计算精度。 This paper addresses the multi-channel coregistration method for Synthetic Aperture Radar(SAR) images.The proposed method takes advantage of all the coherence information available in the neighboring pixels.And the coregistration of the SAR images is characterized by using the construction data detector matrix via the Root Mean Squared Deviation(RMSD) criterion.Numerical results on the simulated data and real data demonstrate the efficiency and precision of the proposed method.
