Radar Cross Section Measurements on Wind Turbines in VHF Band

This work is using a new method allowing to identify reflecting objects in the surrounding area of Doppler VHF Omnidirectional Radio-range (DVOR) transmitters. It is based on a bi-static, partially cooperative Radar application. Here, this method is applied – using received signal power measurements – to derive a quantitative value of an equivalent radar cross section (RCS) of wind turbines. The analysis is focussed on wind turbines in a distance of 5 to 12 km around a DVOR transmitter in Hehlingen, Germany.
