Numerical Simulations of Environmental Distortions by Scattering of Objects for the Radar - SSR and Flat Roofs, RCS and Windturbines

Two cases of potential distortions of radar by environmental objects are introduced and theoretically and numerically analyzed. 1) Metallic flat roofs and the SSR/MSSR with regard to false interrogations and monopulse angle error. 2) Wind turbines and its representation by the radar cross section (RCS) for the radar and in particular for the weather radar. It is outlined that the flat roofs of buildings are acceptable without scattering fences and that the RCS is not applicable for objects on the ground such as for the Wind turbines
