A Review of the Austin RCS Benchmark Suite: Next generation benchmarks to enable CEM performance benchmarking

This article reviews a recently developed benchmark suite for quantifying the performance of alternative computational approaches to solving radar cross-section (RCS) problems in aerospace applications. The Austin RCS Benchmark Suite 1) contains 20 problem sets, with 1,303 unique benchmark scattering problems, whose geometries, material properties, excitations, and quantities of interest are precisely defined; 2) organizes the problems along six dimensions according to the difficulty of computing their solutions; 3) provides reference RCS results for a select subset of the problems in each problem set, totaling 83 unique problems with reference results, obtained from full-wave computations in addition to analytical or measurement results; 4) includes models and sample meshes that define complex geometries as well as equations that define complex material properties for the problems that are most difficult to replicate independently; and 5) is available in online repositories.
