Model the radar signatures of electrically very large targets and scenes with the powerful HFSS SBR+ solver. Engineers can easily perform fast radar cross section (RCS) calculations to detect objects such as aircrafts, vehicles and ships, as well as design these objects to minimise radar detection.
With the integration of HFSS SBR+, Ansys HFSS is empowered with new capability to model radar signatures of electrically very large targets and scenes. Shooting and bouncing rays (SBR) is a ray-tracing technique based on Physical Optics (PO), which has been extended to multi-bounce interactions through Geometric Optics (GO) ray tracing. HFSS SBR+ is suitable for efficiently solving electromagnetic problems that are hundreds and thousands of wavelengths in size. The integration of HFSS SBR+ to the available high-frequency EM solver technologies in Ansys Electronics Desktop allows radar designers to apply the best simulation technologies for predicting radar signatures of structures ranging from sub-wavelengths to kilo-wavelengths. HFSS SBR+ is ideal for the design of collision detection and avoidance systems and stealth technology.
Powered by advanced, edge diffraction physics from the PTD and UTD frameworks, HFSS SBR+ provides accurate and efficient large-scale electromagnetic modeling for structures containing metals and dielectrics, as well as structures with dielectric losses, multi-layer dielectrics and absorbing materials. Ansys now provides a single framework for all high-frequency EM solvers to facilitate a smooth and unified workflow, for solving these complex electromagnetic problems. Additionally, for radar signature analyses, HFSS SBR+ features monostatic and bi-static RCS modeling capabilities with the implementation of plane wave excitations.
