Radar Cross Section Simulation using Ansys HFSS Software

The Radar Cross Section Simulation using Ansys HFSS™ high-frequency electromagnetic simulation software course focuses on radar cross section applications using the shooting bouncing rays (SBR) formulation. Initial hands-on simulation workshops cover monostatic and bistatic RCS (Radar Cross Section). Lecture and later workshops also cover radar signature imaging applications including range profile, waterfall plots, and ISAR (inverse synthetic aperture radar). These imaging applications take advantage of HFSS ACT wizards RADARpre and RADARpost, which are described in the course. There are also technical descriptions of the background and usage of PTD (physical theory of diffraction), related wedge settings, the development of SBR+ surface currents on scattering geometry, and UTD (uniform theory of diffraction).

The Radar Cross Section Simulation using Ansys HFSS Software course is ideally suited for radar signature engineers experienced with Ansys HFSS software for antenna applications. The initial workshops describe all necessary steps, making this course accessible to new Ansys HFSS software users with any prior EM (electromagnetic) antenna simulation experience.

Learning Outcomes: 

Following completion of this course, you will be able to:

• Set up radar cross section simulations using the SBR+ (shooting bounding ray) solution type
• Plot 2D and radiation pattern simulation results
• Simulate and plot 3D monostatic RCS “fuzzballs”
• Compare SBR+ formulation with IE (integral equation) formulation using Hybrid regions
• Use ACT wizards to set up range profiles, ISAR (inverse synthetic aperture radar), and waterfall plots.

Prerequisites:

Prior experience with Ansys HFSS software and antenna related applications is strongly recommended. Knowledge of radar cross section engineering principles and basic electromagnetic principles, including diffraction, are presumed.

Please Note: These training materials were developed and tested in the 2023R2 release.
