Reconstructing stratified permittivity profiles using super-resolution techniques

This paper describes a technique for reconstructing one-dimensional stratified permittivity profiles. The proposed technique is based on the inversion of the measured frequency-domain reflection coefficient of the profile into a virtual time domain. The inversion of the reflection coefficient is based on the super-resolution technique root multiple-signal classification. The advantage of using this technique is its ability to remove the sidelobe effect caused by the limited measurement bandwidth. Measurements using different materials have been carried out to validate the quality of the proposed technique
