Hello, I want to calculate the admittance function for two grids ( g(x,y) Bouger anomaly and h(x,y) topography). It is defined as: (GH*)/(HH*) where G(kx,ky) and H(kx,ky) are in the fourier space and () means average . The term (HH*)is the Radial Average Spectrum that can be calculated using MAGMAP, and (GH*) is the…
Dear community, is there a way to calculate the power spectrum of a 2D grid/1D profile in order to get an overview of the wavelength Distribution, e.g. in the topography? I am aware of the Radially Averaged Power Spectrum Option in MAGMAP for depth-to-basement estimates but this does not help here. Cheers, Martin
