Using HyperWorks to Generate Electrically Large Surface Meshes for Radar Cross Section or Antenna Placement Simulation
Radar Cross Section (RCS) and installed antenna placement are important parameters for aircraft designs. RCS is a measure of how detectable an object, such as an aircraft, is with radar. A large RCS indicates that an object, such as a jet aircraft, is easily detected.
SELEX Galileo used HyperWorks to generate arbitrarily large surface meshes, with defined electrical properties at the element level, for use with electromagnetic (EM) solvers to calculate either RCS of an aircraft or to determine where to place an antenna for optimum performance.
For this case study a fast-jet aircraft with approximately 100 million mesh elements was assessed for radar tracking and avoidance capabilities.
