%T An integrated stochastic multi-scaling strategy for microwave imaging applications
%U http://www.eledia.org/students-reports/515/
%X This work presents an improved Multi-Scale algorithm for microwave imaging of two-dimensional scatterers. The proposed methodology includes a feedback between high- and low-resolution reconstructions in order to correlate the iterative reconstruction steps. Towards this end, the appealing features of a Particle Swarm-based algorithm are fully exploited. Such an integration is aimed at better matching a suitable representation of the unknowns with the global optimization properties of the stochastic optimizer to allow faithful reconstructions.
