Wind farm turbines create a Doppler effect as they rotate, creating a potential radar blackout zone. Raytheon is using hardware and software to detect the turbines on radar systems and eliminate interference with radar displays. U.S. Air Force

The U.K.'s National Air Traffic Services awarded Raytheon Co. a contract to conduct software modeling and field trials of technology that minimizes the effects of wind turbines on radar signals. Wind farm turbines create a Doppler effect as they rotate, creating a potential radar blackout zone. The Raytheon solution uses hardware and software to detect the turbines on radar systems, eliminating interference with radar displays. Under the $6.5 million contract, Raytheon will develop and test advanced mitigation algorithms within its S-band approach and L-band en route primary surveillance radars. System testing will take place in the U.K. and the Netherlands.
