Abstract:Considering shortcomings of conventional search methods in airborne gravity measurement data processing, such as slow search speed, low correct rate and poor applicability, a new method, the ‘sliding window search method’ is proposed. The main line point is regarded as the search center and the main and sub line points are searched in a certain width of search box. The adjacent measuring points detected in the main and auxiliary lines form a line segment, and the intersection and discrepancy are determined. Through practical examples, the sliding window search method is discussed and analyzed from the aspects of search time and accuracy. The results show that the proposed method is simple and efficient, the searching efficiency of cross-point is improved and the workload is reduced significantly.
