Abstract
B017 Focusing inversion technique applied to radar tomographic data Summary 1 Traveltime tomography is a very effective tool to reconstruct acoustic seismic or electromagnetic wave speed distribution. To infer the velocity image of the medium from the measurements of first arrivals is a typical example of ill-posed problem. In the framework of Tikhonov regularization theory in order to replace an ill-posed problem by a well-posed one and to get a unique and stable solution a stabilizing functional (stabilizer) has to be introduced. The stabilizer selects the desired solution from a class of solutions with a specific physical and/or geometrical property;
