Abstract

This work presents shape reconstruction results using TE experimental scattering data of a perfect electric conducting (PEC) cylinder. The level set method combined with the method of moments is used for the reconstruction. The experimental data are collected using two ultrawideband strip-fed dielectric resonator antennas rotating around the target. The removal of the drift noise is achieved through spatial low-pass filtering, which is a key element to improve the reconstruction.
