Correlative analysis of obliquity-scan multi-section and the applied effect

Processing method of multi-section correlation is a kind of effective method of controlling disturb.This paper is based on the basic principal of correlative analysis in controlling disturb, it extends this method through the several aspects of two-dimension interpolation, revising background, tracing the direction of abnormity and processing negative abnormity etc, in order to made it be fit for the complicated instance. At last, it proves the effectiveness of this method through examples.
