Fast Wide-Band RCS Analysis of the Coated Target Based on PBR Using EFIE-PMCHWT and the Chebyshev Approximation Technique
نویسندگان
چکیده
The Chebyshev approximation technique (CAT) combined with the MoM based on electric-field integral equation (EFIE) and Poggio–Miller–Chang–Harrington–Wu–Tsai (PMCHWT) is proposed to efficiently calculate wide-band radar cross-section (RCS) passive bistatic radars (PBR). EFIE-PMCHWT equations can be used analyze electromagnetic scattering of coated targets. combination CAT only requires computing electric magnetic currents at a few frequency points, which employed obtain over entire band. In this study, RCS values target calculated by hybrid EFIE-PMCHWT-CAT (PBR) were found consistent that EFIE-PMCHWT. validity method verified several numerical examples. Compared conventional method, greatly improve efficiency for problems wide
