Regularized Focused Inversion of Magnetic Gradient Measurements in Archaeology

B027 REGULARIZED FOCUSED INVERSION OF MAGNETIC GRADIENT MEASUREMENTS IN ARCHAEOLOGY SUMMARY 1 A regularized inversion algorithm was developed to invert the magnetic vertical gradient measurements for archaeological purposes. The algorithm uses constrains on the susceptibility contrast of the structure’s material to obtain a focused image. An approximate model was used to control the inversion result and to prevent unreliable and unstable inversion results. The Tikhonov parametric functional was used with a minimum support stabilizing functional for the model norm to yield a highly focused solution. The regularization parameter was selected according to the best trade-off between the lowest misfit and
