Abstract：The normalized total gravity gradient approach is a gravity inversion approach that rose in 1.980s, the key operation of which is downward continuation and derivation. A most of the available downward continuation approaches is fulfilled in wavenumber domain, which affects the effect of normalized total gradient approach because of poor stability and is difficult to be generalized. Based on original Hilbert transform solving normalized total gravity gradient, the paper uses a new and stable downward continuation algorithm----iteration to replace original downward continuation operator in wavenumber domain, which improve the precision and stability of computation. The model test and real data application showed significant improvement of effects.
