Abstract:
     Disclosed is a method for improving heavy magnet abnormal resolution. The method comprises gridding the heavy magnet abnormal grid data to form regular grid data; performing Fourier positive transformation on the regular grid heavy magnet data and calculating the frequency spectrum of the original data; analyzing spectrum, signal and the noise distribution area to identify filtering parameter; expanding upward with parsing method; returning downward with difference method; repeating the expanding upward and returning downward processes p times and be multiplied with the filter operator of the broad sense vertical n times differential coefficient; after Fourier transformation, calculating the processed data; drawing the two-dimensional or three-dimensional graphs of the processed data.
