Radar Cross Section / Scattering

The scattering performance of an object describes how energy is scattered when the object is exposed to incident electromagnetic fields.

Applications include mono- and bi-static radar cross sections of defence platforms, scattering from wind turbines and optimisation of other radar systems like automotive collision detection systems. Feko’s high frequency methods are used to solve these typically electrically large, platforms.

Key features:
  • The multilevel fast multipole method (MLFMM) is used to efficiently simulate electrically large platforms.
  • True hybridised, asymptotic solvers for simulation of electrically very large platforms.
  • Model decomposition allows equivalent representation of transmitter / receiver antennas to reduce computational requirements.
