Overview

Comparative analysis reveals that polarimetric features improve oil spill detection, highlighting the importance of incident angle.

Key Points

  • This research aims to evaluate the performance of polarimetric synthetic aperture radar features in detecting different oil slick types under varying incident angles.
  • Utilized RADARSAT-2 images from an oil-on-water experiment in the Norwegian North Sea.
  • Compared polarimetric features based on oil slick type and incident angle.
  • Evaluated detection performance related to scattering mechanisms.
  • Incident angle influenced polarimetric features and detection performance, especially for low oil–water contrast at larger angles.
  • Robust polarimetric features were effective across various incident angles.
  • A combination of scattering entropy H and modified anisotropy A12 provided strong performance in detecting oil spills.
