• Simulation of antenna and structure interactions
• Telecom in urban and indoor propagation conditions

 >  Defense

• Mono and bistatic Radar Cross Section (RCS) prediction of complex targets (aircraft, UAVs, terrestrial vehicles, ground infrastructures...)

• Radar detection performance prediction according to weather conditions
• Synthetic Aperture Radar (SAR) and Inverse Synthetic Aperture Radar (ISAR) simulation: new modelling radar from Numerical Model of Terrain (NMT) to SAR images

> EM Environment

• EM field distribution
• External Electromagnetic Compatibility (EMC)

Keywords

• Radar simulation, RCS, SAR, electromagnetic, antenna, propagation, telecommunications, radio waves, ray tracing, EMC, radiation prediction

Advantages

FERMAT/ SE-RAY-EM is an asymptotic modeling suite in near or/and far field interaction of an EM wave and its environment (up to mm wavelength) predicting reliable electromagnetic fields and including:

• Atmospheric effects taken into account
• Modeling antenna diagram both in transmitting/receiving modes
• Roughness surface management.
• Radar modeling (transfer function and wave form)

Simulation code

A solution to every requirement:

• The commercial simulation code SE-RAY-EM is continuously upgraded, maintained and distributed by OKTAL SE, www.oktal-se.fr with following aspects:
  • Can deal with complex objects, complex environments and complex targets in a complex 3D scene
  • Can deal with OpenFlight, OpenInvertor, DXF, VRML and 3DS CAD formats
  • Scenarios creation and management tools
  • Can handle mobile objects and mobile sensors in the scene
  • « Forward » fast and modular ray-tracing method
  • « A symptotic » electromagnetic model for radio wave propagation, reflection, scattering, diffraction and transmission
  • Dedicated models for clutter materials including speckle effects
  • « Phase textures » to simulate local rough surfaces
  • A complete and well documented validation process
  • Well documented physical formulations
• FERMAT, a matching to your needs can also customised by studies jointly by ONERA and OKTAL SE
