Aveillant’s 3-D Radar Distinguishes between Wind Turbines and Aircraft

April 5, 2012

Aveillant, a spin-off company from France-based technology engineering specialist Altran, is developing a new radar designed to distinguish between aircraft and the rotating blades of wind turbines, eliminating the potential confusion wind farms could cause in ATC and allowing wind farms to be built closer to airports.

On today’s ATC displays, a wind turbine appears exactly as an aircraft. ATC radar does not know the height of an object, unless it has a transponder. Since not all aircraft have transponders, it is important that primary radar continues to operate in wind farm areas, Craig Webster, Aveillant business development director, explained. Aveillant’s radar can locate “non-cooperative objects” (aircraft without a transponder) amidst clutter such as wind farms.
