7.2.3.2.2 Military Aviation: Operation and Maintenance

NYSERDA states: "During operation, impacts on radar within and near WTGs can mask real structures or produce false echoes."

The document also notes that "The USCG found moderate impairment to radar of vessels operating within the array but concluded that the impact could be reduced through mitigation.
Typical mitigation measures identified included traffic management measures, such as recommended vessel routes and specially marked traffic lanes, establishment of a control center to maintain monitoring during operation, and educational measures to provide mariners information on navigation safety issues related to travel within and near the wind farm" (NYSERDA, 2017, page A-31).

In a research study for the DOE, scientists at the University of Texas at Austin evaluated the impact of large wind farms on various parameters, including radar.

The paper indicates that "marine navigation radars and ocean monitoring HF sensors may experience interference under certain proximity and operating conditions as the result of typical wind farm configurations" (Ling, Hamilton, Bhalla, Brown, Hay, Whitelonis, Yang, Naqvi. 2013, p. 28).
