摘　　要：An efficient extrapolation technique of Radar cross-section(RCS) combines with Poggio-MillerChang-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(Mo M). 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.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 three- dimensional homogeneous lossy dielectric objects.
