More Information
Computing electromagnetic scattering and radar cross section for electrically large objects like aircraft presents major computational challenges. This whitepaper compares numerical methods for efficiently simulating RCS of large aerospace structures: Method of Moments (full-wave), Extrapolated MoM, Physical Optics, and hybrid techniques. Simulations of a 40-meter civilian transport aircraft at 0.5-1.0 GHz demonstrate that approximative methods achieve accuracy comparable to full-wave solutions while dramatically reducing computation time, making high-fidelity electromagnetic analysis practical on standard desktop hardware.
