At typical radar frequencies a wind turbine has a large radar-cross-section (RCS) and due to the movement of the blades, the wind turbine generates a Doppler spectrum. This scattering behaviour has caused concern with radar operators, particularly those working with safety critical radar and national defence. This paper presents results from a modelling tool developed by BAE Systems, Advanced Technology Centre, which models the effect of a wind farm on a radar system. This paper discusses the development of the model and provides an example analysis using a case study, which highlights the problems associated with placing a wind farm near a radar system.
This report was commissioned by Ofcom to provide an independent view on issues relevant to its duties as regulator for the UK communication industry, for example issues of future technology or efficient use of the radio spectrum in the United Kingdom.
