Offshore wind farm study finds radar coverage drops and ghost targets rise
At a distance of 5 km, effective radar coverage fell by 6.9%, while blind spots increased by 14.9%, the study found.
A new study warns that offshore wind farms can interfere with shore-based radar by reducing effective coverage and creating blind spots where targets are harder to detect, according to SCMP Economy.
The researchers reported that at a range of 5 km, effective radar coverage fell by 6.9%, while blind spots increased by 14.9%.
The study also says large wind turbine arrays could generate false “ghost” targets through reflected radar signals, which could complicate vessel detection in coastal waters.
The research was conducted by Professor Liu Zunnian and his team from Qingdao Technological University, the Yantai Communication Centre of the Beihai Navigation Security Centre under China’s Ministry of Transport, and was published online last month in the peer-reviewed Chinese journal Radio Engineering.
