Abstract :
A dyadic contrast function for Radio Frequency Tomography is developed. The goal of such contrast function is to allow the reconstruction of the orientation in a three-dimensional space of thin-elongated metallic scatterers. This is accomplished by modeling the scatterer with a dyadic matrix. An intuitive visual representation of the target is obtained performing the eigen-decomposition of such dyadic matrix. Numerical results to validate the approach are presented.
