| 摘 要： | 针对常规极化干涉SAR配准仅仅用一个通道的极化数据进行干涉数据对配准,导致配准精度不高的问题,提出了一种利用Cameron相干目标分解进行极化干涉图像对的配准方法。该算法充分利用了全极化数据丰富的信息,进行极化干涉图像对的配准。利用SIR-C天山地区的数据对提出的算法进行了验证,结果证明该算法能提高配准的精度和鲁棒性,有利于后续的数据处理。

| Abstract: | Conventional polarimetric interferometry SAR image coregistration methods usually use the data of one polarimetric channel only,which is not very accurate.In order to solve this problem,a new coregistraion method making use of Cameron’s coherent target decomposition theory is proposed.This method makes use of full polarimetric interferometry SAR data which contains very abundant information to perform coregistration.Finally,the proposed method is applied to the PolInSAR data of Tien Shan area acquired by SIR-C,and it is verified that the proposed algorithm is more accurate and more robust.It is beneficial for the following data processing. |
