SAR图像的几何校正

Geometric Rectification of SAR Image

  • 摘要: 采用Konecny等提出的合成孔径雷达(SAR)的构像几何模型并结合数字高程模型(DEM)进行了SAR图像的几何校正,取得了较好的效果。此外,在定向元素的解算中引入了岭估计,较好地克服了由外方位元素间的强相关引起的方程病态。

     

    Abstract: In this paper,the mathematical model of SAR image,which is provided by Konecny,is used to finish the geometric rectification and a satisfactory result is achieved.Further more,the ridge estimate is used to resolve the orientation parameters.It can reduce the correlation and the disadvantages in previous methods.
