Validation of Austin RCS Benchmarks Using Altair Feko

University of Texas Austin has created a computational electromagnetics benchmark suite to validate both current and future electromagnetic radar cross-section methods. Austin Benchmark Suite consists of four geometries with various material assignments: sphere, plate, almond, and aircraft.

A key benchmark in the suite is aircraft models, one with open ducts and the other closed ducts for the intake/exhaust system. These benchmarks are developed by UT Austin in collaboration with Lockheed Martin Aeronautics’ EXPEDITE program to create an open-source aircraft model to validate various CEM methods.

In this white paper, we present validation of the aircraft models in Austin RCS Benchmark Suite with Altair Feko.
