| In geoid computation and gravity field modeling, downward continuation of the gravity field functional is done by solution of the Able-Poisson integral equation. Since the Able-Poisson integral equation is one type of Fredholm integral equations, this equation is ill-posed and need to be regularized to find the best solution. In this paper, 6 usual regulation methods are compared together on simulated data in a case study in south of Iran. The result showed the Koch- Koshe and Philips-Tikhonov with L-curve Criteria methods have the best solution in case study area (CoastalPars). |
