Summary:
Systems, such as navigation, landing, radar and communication systems, rely on the physics of antennas and propagation and signal processing. Their operational electrical performance is determined by the intended radiation and by the scattering of distorting objects, so-called multipath. In case of airport development or building plans close to these systems (Fig. 1), the expected electrical performance has to be predicted by appropriate means, i.e. numerical system simulations. The scattering analysis is an integral part of these system simulations which result in the decisive system parameter, may be the angle or range error used by the aircraft or by the radar depending on the system. The field analysis of the scattered or superposed field by itself does not help in almost all cases and tasks. The system simulation needs the processing of the field-quantities. The scattering analysis of potential "false targets" or of the range reduction by shadowing for a radar are of interest too. Mostly these simulations are processed in advance before the objects are built and appear on the airports or in some close distance of the installed systems [1] ? [5]. Due to the system risks, the simulations must be reliable and sufficiently accurate and, also, the numerical effort must be minimized and should be justified and tolerable.
