How to Accelerate Radar Cross Section Simulations for Large Structures

The white paper discusses methods to accelerate radar cross section (RCS) simulations for large aerospace structures, crucial for aircraft design and defense applications. It compares techniques like Method of Moments, Extrapolated MoM, Physical Optics, and hybrid approaches for efficient RCS analysis. These approximative methods significantly reduce computation time while maintaining accuracy, making high-fidelity electromagnetic analysis feasible on standard desktop workstations without the need for supercomputing resources. The study demonstrates the practicality of these methods by simulating a 40-meter civilian transport aircraft at 0.5-1.0 GHz, showcasing their effectiveness in reducing computational costs and time.
