Radar return reduction for wind turbines using bump structures

Wind turbines are massive electrical structures. They produce large returns when illuminated by radar waves. These scatterings have a great impact on the operation of surveillance, air traffic control and weather radars. This paper presents two geometric modelling methods for reshaping wind turbine...
