mitigate clutter from wind turbines. Several solutions have been pro-

posed to mitigate this problem including :
Changing the Doppler signature of blade by making them less

reflective to radar signals
Changing digital processing software to recognize wind tur-

bines
Curtailing production during significant weather events such

that uncluttered data can be obtained
