Introduction

In this article, we compute the bistatic radar cross-section (RCS) of a Dassault Mirage III type fighter aircraft at 850 MHz with EM.Tempo. At 850 MHz, considerable computational resources are required to compute a full-wave result with EM.Tempo's FDTD solver.

Computational Environment

The Mirage III has approximate dimensions (length,wingspan,height) of 15m x 8m x 4.5m.
