Radar Cross Section

Radar Cross-Section (RCS) measurements are essential for aerospace engineering in the development of radar stealth technology. In order to calculate RCS, engineers must simulate far-fields and radiation scattering, which can be extremely computationally expensive.

VSim has a unique implementation of a “Kirchhoff Box” that drastically diminishes the simulation size and time. With the Kirchhoff Box, far-field patterns, even for electrically large simulations, can be obtained in a matter of hours even on a small machine.

VSim can model EM radiation propagation and scattering, but it can also compute radar cross sections and specific absorption rate (SAR). Radar interactions, including ground penetrating radar, can also be simulated in VSim with the total-field/scattered-field method.
