Status of advanced scattering distortion system analysis for navaids and radar - examples of A380 and wind turbines

Modern systems, e.g. navigation, landing, radar and communication systems, rely on the physics of antennas and propagation. Their electrical performance is determined by the intended radiation and by the scattering of distorting objects. The scattering analysis is an integral part of the system simulations. The modeling of the antennas, the environment, the distorting objects and of the system itself are the basic steps of the simulation process. This paper describes the aspects of state-of-the art system simulations by evaluating actual examples, such as the new A380 with respect to the landing system ILS and wind turbines WT to radar systems, in particular to weather radar.
