A research team led by Professor Liu Zunnian from Qingdao Technological University has published findings suggesting that offshore wind farms pose technical challenges for coastal radar infrastructure. According to the study, which appeared in the journal Radio Engineering, the physical presence of large wind turbines can obstruct radar signals, leading to reduced detection capabilities for shore-based systems.

The study quantified these impacts, noting that at a distance of 5 kilometers (approximately 3 miles) from a radar site, effective coverage dropped by 6.9 percent. Furthermore, the researchers observed a 14.9 percent increase in radar 'blind spots'—areas where the radar is unable to detect objects. Beyond simple signal blockage, the study highlighted the emergence of 'ghost' targets, which are false readings caused by radar waves reflecting off the rotating turbine blades. These technical interference issues could complicate maritime surveillance and safety operations in areas where wind energy projects are situated near critical radar installations. While the study focuses on the technical limitations imposed by turbine placement, it underscores a growing concern for maritime authorities who rely on clear radar data for navigation and security.
