The present invention is concerned with improving the reliability of returns from aircraft surveillance radars, and particularly with removing returns from non-aircraft targets such as, but not exclusively, wind turbines. The invention provides a wind turbine filter. The wind turbine filter is only concerned with radar returns or plots within the area requiring enhancement - i.e., in this example, within the wind farm zone. This zone is a zone within the overall coverage of the local radar - radar A as well as the remote radars - in this case two remote radars, radar B and radar C. |
