| Abstract: | The Paper presents a set of variable transform,or the non-singular transform,that can make the singular integrals of terrain corrections non-singular. The formulations and tests with analytic terrain representations and real terrain data in the peper illustrate surprisingly that the proposed varisble transform in the poper is an efficient approach to the precise evaluation of terrain corrections. |

| Keywords: | terrain corrections the Earth's gravity field singular integrals |
