Electromagnetic Imaging of Discrete Wire Scatterers via MUSIC Algorithm: Preliminary Experimental Results

Qualitative electromagnetic imaging of perfectly conducting electrical wires with multiple signal classification (MUSIC) algorithm is considered in 2D cylindrical coordinates. The motivation arises from safety/security applications where deployed electrical wires are required to be remotely sensed in a near real time setting. The results demonstrate that the algorithm can rapidly reconstruct the 2D coordinates of the electrically conducting thin wire scatterers in the measurement domain.

I. Introduction

In electromagnetic imaging the region of interest is illuminated with electromagnetic waves by one or multiple antennas. The scattering field is later collected by one or multiple antennas to generate an image representing dielectric parameters of the region of interest. The aim is to reconstruct the geometrical or the electrical properties of the targets [1]. Generally, electromagnetic imaging methods can be classified as either quantitative or qualitative methods. In quantitative methods exact electrical properties of the region of interest is regenerated whereas in qualitative methods geometrical parameters like shape and location is aimed to regenerated.
