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. Or, measured in terms of freespace wavelength at 850 MHz, 42.5 lambda x 22.66 lambda x 12.75 lambda. Thus, for the purposes of EM.Tempo, we need to solve a region of about 12,279 cubic wavelengths. For problems of this magnitude, a great deal of CPU memory is needed, and a high-performance CPU is desirable to reduce simulation time.
