Cassidian improves performance of air traffic control radars in eliminating wind turbine interference
Cassidian has developed a technical solution to largely eliminate interference to air traffic control radars caused by wind turbines.
As a result of a multi-year research project carried out in cooperation with the German Federal Ministry for the Environment (BMU), the EADS defence division now has developed a solution based on changes to the radar antenna as well as to the signal and data processing.
On the one hand, using a controllable antenna diagram, a large part of the interfering radar echoes from wind turbines can be masked out. On the other hand, using pattern recognition algorithms, the radar system is able to reliably distinguish aircraft echoes from interference signals, even in the immediate vicinity of wind turbines.
The effectiveness of these procedures has been proved in extensive flight tests at Büchel air base in Germany. This new technology will facilitate the extension of wind parks in the vicinity of airports while taking account of flight safety. It will be possible to use this new technology within a period of two years.
