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.
