Abstract :
This paper presents a very simple and effective numerical approach for an electromagnetic inverse scattering systems (EMISS) characterization based on 2D Green´s function analysis. For this purpose, a number of Green´s function matrices are constructed for various random distributions of source elements and observation point positions. We have employed the numerical rank of the Green´s function matrices as the degree-of-uniqueness of the EMISS. Plotting the degree-of-uniqueness vs. the number of source EMISS elements enables us to compare different EMISS settings and find the optimum one for an EMISS implementation. The extensive simulation results confirm the effectiveness of the Green´s function characterization curves.
