摘要
重磁数据处理的根本任务是从观测数据中提取更多的信息,以丰富重磁异常解释的方法,提高地质解释结果的准确性和可靠性。希尔伯特变换是数据处理的一种方法,近几年在重磁异常中已有所应用,主要有利用希尔伯特变换进行二维位场分量的互算;通过二度体重磁异常的某一分量与其希尔伯特变换来反演异常体埋藏深度和产状要素。
Hilbert transform is a method for digital processing. This paper presents two types of Hilbert transform formulas and their calculating formulas in freqency domain based on Fourier transform. Hilbert transform formulas of △T1 and AT2 of the total magnetic effect of some two-dimensional magnetic bodies are obtained according to the correlation of component magnetic effect. A new procedure for AT interpretation is developed using some special points and the intersection points of △T1 △T2 and △T curves. The validity of the procedure is tested on theoretical models and a field example.
