Radar cross-section & stealth: how Ansys helps

Radar cross-section decides whether a platform is seen. Range time on a real RCS chamber is scarce and classified, so shaping and radar-absorbing-material choices are proven in simulation first.

Illustrative simulation render. Actual studies are built to your geometry and requirements.

The Ansys tools that model it

HFSS — Full-wave and SBR+ asymptotic solvers predict monostatic and bistatic RCS of realistic geometries across frequency.
Savant — Physics-based ray-tracing scales RCS and antenna-in-situ analysis up to electrically enormous platforms.
Mechanical — Ties signature-driven shaping back to a manufacturable, structurally sound airframe.
