| Abstract | The problem of downward continuation of potential fields is being considered. The basic approach involves computation in real space using a power series expansion. The computation of the derivatives required for evaluating the series is carried out on the basis of two approximation methods, viz. (1) polynomial method, and (2) application of band-limited functions. The band-limited approach is also applied to the problem of transforming the direction of the source magnetization, that is, to the problem of transforming a given magnetic field to the pole. The quality of these results is considered in two ways: (1) the frequency response of the derived convolution coefficients are compared with the analogous system functions of the linear filter method; and (2) the methods are applied to artificial magnetic test cases. Good quality results are obtained using these methods. The methods are also applied to a portion of field data. |
