Abstract
Accurate detection of marine oil spills in Synthetic Aperture Radar (SAR) imagery remains a major challenge. Mineral oil and naturally occurring biogenic slicks often produce nearly identical signatures in SAR imagery, despite their fundamentally different environmental implications. This review critically evaluates the physical processes governing SAR-based oil spill detection and asks whether secondary dielectric and polarimetric effects can overcome the inherent limitations of single-channel intensity data.
The analysis reveals two key findings. First, while wave damping ensures high contrast under optimal wind conditions (3–10 m/s), secondary dielectric effects only emerge in thick emulsions (>0.4 mm). These conditions are rarely encountered in operational scenarios. Second, instrument noise floors (NESZ) severely compromise polarimetric retrievals, limiting their reliability.
Together, these findings provide a practical framework for interpreting SAR imagery. They also guide the integration of AI-driven classification with multi-sensor fusion (X-, C-, and L-band) to reduce false alarm rates in operational monitoring systems.
