| 英文摘要 | Downward continuation has commonly been used in gravity, magnetic data processing and interpretation, but the instability restricts its application in data processing and inversion. This paper introduces a method for downward continuation of potential field data, which is based on the ideas of iteration method for filtering of smooth compensation and downward continuation, and realizes more stable downward continuation by this compensation method. We also discuss the compensation method for the downward continuation in the frequency domain, and give the result of its frequency response. Furthermore, we analyze the filter characteristics of the downward continuation factor. The computations of model and practical data demonstrate the effect of the stability and long downward continuation distance, and also have high accuracy downward continuation results. Meanwhile, we substitute this stable downward continuation for the intrinsic operator in the iterative procedure of Parker-Oldenburg method and strengthen the stability of inversion. The procedure of density interface inversion has been examined effectively by computing Moho depth as a practical geological example. |
