Validation of Austin RCS benchmarks using Simcenter Feko

Accurate radar cross-section (RCS) prediction is critical for aerospace and defense applications. The University of Texas at Austin developed an open-source computational electromagnetics (CEM) benchmark suite in collaboration with Lockheed Martin Aeronautics to validate current and emerging RCS simulation methods across four geometry types: sphere, plate, almond and aircraft.

The challenge of confirming simulation accuracy

A key challenge in RCS simulation is confirming that software results match real-world measurements across different materials, frequencies and configurations. The Austin RCS Benchmark Suite addresses this by providing measured lab data from the EXPEDITE program alongside aircraft models featuring both open-duct and closed-duct intake and exhaust configurations.

Putting Simcenter Feko to the test

This white paper presents the validation of Simcenter™ Feko™ against the Austin RCS Benchmark Suite aircraft models, comparing simulation results directly with EXPEDITE measured data and ARCHIE-AIM simulation data. Simulations were conducted across multiple frequencies and material types including Perfect Electric Conductor (PEC) and resin configurations using the Method of Moments (MoM) solver in Simcenter Feko.
