The impact of an adjacent wind farm operation on telecommunication signals is that it induces electromagnetic interference (EMI) in radar, television and radio signals, resulting from the complex rotating blade's geometry of the wind turbines. . The purpose of this project is to assess the impact of wind farm interference on interoperable train control (ITC) communication system at 220 MHz. In this project, Meteorcomm's (MCC) Research team performed field measurement at Tehachapi Pass Wind Farm in California, characterized wind farm. . This paper describes how these problems can be identified and avoided during the design and site selection of the wind power facilities through analysis and measurement methods used successfully at various locations throughout the United States. There are three mechanisms by which wind turbines may cause interference: reflection or scattering, diffraction and near. . Wind turbines are huge signal reflectors of greater dimensions than the targets that radars aim at, and therefore, their presence may hide weaker signals from smaller targets. Additionally, the rotating blades generate a Doppler shift also detected by the radars. A sample of these are below: - Study: Tall structures and their impact on broadcast and other wireless services.
