The aim of this paper is to estimate the interaction between a Savonius wind turbine and a radar by means of simulation using Comsol Multiphysics 4.3a. Radar interference depending on each major part of a horizontal axis wind turbine is overviewed and studied. These results are then qualitatively compared with radar interference caused by the S-shaped Savonius wind turbine. It is shown that the S-shaped Savonius wind turbine causes noticeable interference on radar performance, compared to horizontal axis wind turbine.
