In this contribution, preliminary analyses are performed on the use of focused beams for imaging of PEC targets. In particular, the data collected in case of Bessel-shaped beam as incident field are processed by means of the well-known physical optics approximation and also by a recently introduced qualitative method, which exploits sparsity regularization and solves the related inverse source problem. A preliminary example against 2D scalar geometry and a C-shaped PEC cylinder is reported and discussed.

Abstract

In this contribution, preliminary analyses are performed on the use of focused beams for imaging of PEC targets. In particular, the data collected in case of Bessel-shaped beam as incident field are processed by means of the well-known physical optics approximation and also by a recently introduced qualitative method, which exploits sparsity regularization and solves the related inverse source problem. A preliminary example against 2D scalar geometry and a C-shaped PEC cylinder is reported and discussed.
