Abstract Using Nettleton's method,the author made filtering separation for amplitude spectra of regional anomalies and local anomalies.In view of the low discrimination velocity of the traditional polygonous filter,the author worked out a calculation scheme for rapid discrimination and made theoretical model verification.The technique was eventually used to process measured gravity data.
