    • Abstract
  • This paper introduces a new algorithm based on EM algorithm to get precise postion and slope. We find the postion of notable geographic characteristic in the SAR image and the contour map. Then the postion of the seed is adjusted. We correct the postion and slope of the seed through iterative computation by cosine backscatter model based on EM algorithm.
