Mapping wind turbine tower locations in Ca Mau coastal region using Sentinel-1 synthetic aperture radar images

Tóm tắt

Ca Mau province is a coastal region with strong and fairly stable winds, less affected by storms. By July 2025, Ca Mau province has 13 completed and operational wind farms. The increasing number of wind energy projects shows that monitoring the development of wind energy projects is essential. The objective of this study is to detect the persistent construction structures on sea, specifically wind towers built off the shore of Ca Mau province. This study used the two-dimensional polarization space method on Sentinel-1 time-series radar images to identify the locations of wind turbine towers off the shore of Ca Mau province. The results showed that the confounding effects of complex variations in incident and azimuth angles of the Sentinel-1 synthetic aperture radar (SAR) images have been completely eliminated. In addition, the method used in this study was successful in mapping persistent construction structures with Sentinel-1 time-series SAR images. The accuracy of results was evaluated by observing and collecting ground truth data in the study area. With very high accuracy, this method can be applied to map the locations of persistent construction structures at sea at other wind farm projects in the future
