Radar and wind turbines — RCS theory and results for objects on the ground and in finite distances

Abstract

This paper describes the application of the numerical scattering analysis embedded into systems simulations for navigation and radar systems. A special focus is on the theory and application and the numerical scattering analysis of the Radar Cross Section RCS for wind turbines WT. WT are installed on the ground and are in the mutual near field of the radar antenna and the WT preventing the reasonable and correct application for practical demonstrated cases. A normalized Back scattering Cross Section BCS is proposed if the ground is included. One example is outlined for a planned wind farm of 6 turbines in large distance of 18km to weather radar WR.
