  • An efficient extrapolation technique of Radar cross-section (RCS) combines with Poggio-Miller-Chang-Harrington-Wu-Tsai (PMCHWT) formulation is presented for the fast analysis by arbitrary shaped threedimensional homogeneous lossy dielectric objects. The PMCHWT formulation obtained in a well-known manner is discretized to matrix equations using the Method of moments (MoM). For the RCS is highly angular dependent as well as frequency, a novel rational function scheme is extended to the induced currents associated with PMCHWT, which can provide fast and accurate radar cross-section computation in both the frequency domain and spatial domain simultaneously. Numerical results are presented for two canonical dielectric scatterers.
