Wind Farms, US ATC, Mode-S Expansion and Declining Air Traffic

摘要

NATS is seeking a solution to the potentially disastrous problem of commercial and military aircraft 'disappearing' in radar blackout zones caused by wind farms. Wind farm turbines create a Doppler effect as they turn and this shows up on radar screens. Aircraft passing through this area can seem to disappear and controllers can lose their exact position. The RAF is concerned that enemy bombers or other aircraft could hide behind interference from offshore wind farms and approach Britain undetected.
