Characterization of lossy layers through monostatic radar measurements

This paper presents an inversion technique based on monostatic radar measurements for the e.m. characterization of lossy slabs. Under the hypotesis of low-loss materials, it is possible to analytically bound permittivity, conductivity and thickness of a slab to the amplitudes and time of delays of the detected echoes. The analysis of various materials has shown that the methodology can provide very good results. It has been anyway confirmed that too high values of conductivity will lead to a significant increase of the errors or even the unfeasibility of the inversion process.
