WebApr 9, 2024 · 4.2.3 Upward Continuation (UC) and Regional-Residual Separation. The UC corresponds to a low-pass filter that attenuates short wavelength anomalies whose sources are near the surface (Jacobsen, 1987). This method allows not only to follow the evolution of a body in depth but also to estimate the average depth of the body (Jacobsen, 1987). WebIn addition to this role as a Wiener filter, the upward continuation operator is given by elementary functions in both space and wavenumber domains, is numerically stable, and is also physically comprehensible when applied to real, nonrandom anomalies.

WebThe Use of upward continuation to certain altitude and wavelength filter is intended to produce appropriate regional and local anomalies. The methods were tested on synthetic models consisting of deep anomaly and shallow anomaly at 500 m and 200 m respectively.
