Ansys HFSS SBR+ Radar Cross Section

Course Overview

The Ansys HFSS SBR+ RCS course focuses on radar cross section applications using the shooting bouncing rays (SBR) formulation.  Initial hands-on simulation workshops cover monostatic and bistatic RCS. Lecture video 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 Extension utilities RADARpre and RADARpost, which are provided and 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 Ansys HFSS SBR+ RCS course is ideally suited for radar signature engineers experienced with Ansys HFSS for antenna applications. The initial workshops describe all necessary steps, making this course accessible to new HFSS users with any prior EM (electromagnetic) antenna simulation experience.

 

Prerequisites

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

Target Audience:

Radar Signature Engineers and Antenna Design Engineers

Teaching Method:

Lecture modules, supplemental videos, and hands-on HFSS simulation workshops.
