A new study finds that turbines can muddle ships' navigational systems, obscuring the location of smaller boats or creating misleading images on radar screens.
that wind turbines can create two different problems. First, their steel towers can reflect electromagnetic waves, interfering with ships’ navigational radar systems in ways that might obscure a nearby boat., in which sound waves shorten as a moving object approaches the observer. In this case, the spinning blades shorten and distort the radar signals sent from passing ships and can produce what’s called “blade flash” on a ship’s radar screen.
In the report, the US Coast Guard raised concerns that the radar interference may also hamper search-and-rescue efforts for ships that get in trouble around wind farms.Bill Melvin
