合成孔径雷达配准方法研究

Research on Synthetic Aperture Radar Registration Method

文章首先回顾了基于强度互相关的配准方法和基于条纹清晰度的配准方法,并分析了合成孔径雷达配准方法存在的共性问题,然后提出了改进的SAR复数影像配准方法,最后通过一个案例进行分析,验证了采用偏移量标准偏差配准的影像在相关值和干涉图相位梯度方面都优于相关值加权方法。

The paper reviewed the registration methods based on intensity correlation and fringe clarity respectively, analysed the common problems of synthetic aperture radar registration method, and then proposed a method of updated SAR complex image registration. At last, the authors through the analysis of a case have proved that the image registrated by offset standard deviation is better than that registrated by correlation value weighted method in regards of correlation value and interferometric phase gradient.
