Wind farm interferences in Passive Coherent Location

Abstract

Rapid growth in the number of wind farms may influence the performance of many radar systems. The radar echoes originating from wind turbine's blades and tower may mask existing objects or generate false plots. In the presented paper the authors analyze the influence of a wind turbine on Passive Coherent Location radars and discuss the effectiveness of simple methods used to overcome problems associated with it. The results of a simulation along with the recorded echoes of the wind turbine gathered by DVB-T based passive radar demonstrator are also shown in the paper.
