Abstract: Oil spill pollution is a severe environmental problem, which persists in marine environment or in inland water across the world. It has grown to an alarming magnitude with increased levels of oil production and transport. Thus, it is important to study and analyze this environmental pollution. The study and detection of oil spills can only be accomplished by satellite microwave remote sensing techniques. As microwaves have unique all weather penetration capability and can be used both in day and night, it does not require illumination of target from the sun. Two types of microwave sensors [Ulaby F T et al. Microwave remote sensing – Active and passive, Vol 1 and 3, 1981] exist: one is passive sensor and other active sensor. Passive microwave sensor is radiometer that operates in the microwave region and detects microwave radiation emitted by the earth surface in addition to passively sensing emissions coming from objects on Earth. Active microwave sensor emits microwaves toward the earth's surface. These microwaves are reflected back from earth's surface and return back to the sensor. In this paper, for the detection of oil spills, data of passive microwave sensors onboard Special Sensor Microwave/Imager (SSM/I) [Hollinger J et al. Special Sensor Microwave/Imager user’s guide, 1987, 120] satellite at 19.3 GHz frequency is used and analyzed. The analyses shows sudden decrease of brightness temperature values in both horizontal and vertical polarization over the oil spill area (Bombay High Area, Arabian Sea) when compared to the brightness temperature values over oil free area in the Arabian sea.
