Optimization of the Experimental Parameters and of the Noise of Scattering Measurements for Inverse Scattering Applications

摘要

This paper presents an attempt to optimize the technical settings of the experimental setup of the CCRM in Marseille in order to reduce the experimental noise and test its influence on inverse scattering reconstructions. This work has been done with the constraint of keeping a Gaussian noise distribution. The reconstructions, obtained from both simulation and measurements of the field scattered by the target under study, a spiral, were obtained with an inversion algorithm based on a Bayesian approach. Moreover, two different reconstructions from measurements are discussed here, with and without taking into account in the inversion algorithm the distribution of the noise affecting the measurements. Some preliminary conclusions are drawn.
