Fast, Spatial Domain Potential Field Modeling

In this contribution we propose an alternative method to the traditional spatial domain technique of prism integration in potential field modeling. The advantages and disadvantages of prism integration as compared to e.g. Fourier methods or wavelet methods are well known. Our aim is to improve the main disadvantages of the space domain methods in order to make them an attractive alternative to FFT based techniques. Our long-range goal is to enhance the flexibility in the complexity of source distribution that can be handled, as well as to significantly improve the computational speed. However, these goals must be achieved without compromising the accuracy of the computed potential field signal. The first numerical experiments reported here were successful in all respects.
