| Abstract: | In this paper we examine the problems in the density inversion from satellite gravity gradient data which including plan model error, the regulation of ill-conditional matrix, the inversion of big matrix, the combination of nonlinear prior data, etc. Using the Tesseroid model we complete the simulation model inversion adding the white Gauss noise based on methods which include general ridge estimation, ART (algebra reconstruction technique) and genetic algorithm. Finally, all the results are compared and analyzed with the prior model.. |
