1. A system for detecting oil spills on the sea surface, comprising:
- a non-polarization reflectivity determining unit that determines reflectivity for each polarization for sea water and oil of a sea surface region on which oil is spilled, using radiance measured by an observation sensor unit of a satellite;
a refractive index operation unit that processes refractive indexes of sea water and oil using vertical reflectivity or horizontal reflectivity determined by the non-polarization reflectivity determining unit; and
an oil detection analysis unit that analyzes the refractive indexes of the sea water and the oil and discriminating a position of the oil.

Abstract
Disclosed are systems and methods of detecting oil spills on the sea surface at night. According to some embodiments, implementations herein involve detection of the polarized reflectivity and the refractive index of the water and the oil using the polarization properties of the electromagnetic waves based on satellite data to accurately and quantitatively detect the position of the oil band spread on the sea.
