An improved and stable downward continuation of potential field data: The truncated Taylor series iterative downward continuation method

Geophysics, 2013
ABSTRACT We present a stable downward continuation strategy based on combining the ideas of the Taylor series expansion and the iterative downward continuation methods in a single method with better downward continuation and/or computer time/memory performance for potential field data containing noise.

Analysis on Convergence of Iteration Method for Potential Fields Downward Continuation and Research on Robust Downward Continuation Method

Chinese Journal of Geophysics, 2009
AbstractGeomagnetic navigation is a new navigation technology and has very important significance for the national defence. Spatial geomagnetic database is a precondition for implementing geomagnetic navigation. Potential field continuation is an effective method for designing geomagnetic database.

Modeling of Seismic Data in the Downward Continuation Approach

SIAM Journal on Applied Mathematics, 2005
Summary: Seismic data are commonly modeled by a high-frequency single scattering approximation. This amounts to a linearization in the medium coefficient about a smooth background. The discontinuities are contained in the medium perturbation. The high-frequency part of the wavefield in the background medium is described by a geometrical optics ...
