| Abstract: | The linear approximation is often implemented for the evaluation ofterrain corrections,which may lead to a bigger error and not achieve the requirement ofthe practical evaluation. In order to make the precise evaluation of terrain correctionspossible,a new variable or a slope variable of k=y/x or k=x/y is introduced, by whichthe singular integral can be convcrted into the non-singular one. Detailed investigationindicates that the linear approximation can not be implemented in the innermost area. |
