Satellite remote sensing method is by satellite monitoring offshore spilled oil, utilize the image processing system of specialty to calculate the oil spilling thickness of imaging moment, this method has low cost, the feature that accuracy is high, but this method is by marine environment, and the impact of the factors such as weather conditions is serious.
Oil film thickness and Spectral Characteristic mainly to combine according to the difference reflection of oil film in spectral region, scattering, absorption characteristic and determine oil film thickness by remote optical sensing method.The optical remote sensing technology being used for detecting oil film thickness at present mainly contains remote sensing method, ultraviolet remote sensing method and laser remote sensing method three kinds.
Infrared remote sensing method in certain thickness situation, absorbs solar radiation according to oil film, and the emittance of a part discharged with the form of heat energy, and heavy oil film shows as hot feature, and intermediate gauge oil film shows as cold feature.This measuring method is cheap, lightweight, without the need to processing aircraft, but affects by the factor of weather conditions, sea situation, and can't detect the thickness of thin oil film.
Although ultraviolet remote sensing method be mainly applicable to thin oil film detection its charge is small, ultraviolet remote sensor easily by external environment impact and produce deceptive information, be difficult to and other Remote Sensing Image Matching.
Laser remote sensing method can the carrying out of round-the-clock, full meteorology be monitored, applied range, but the own wt of laser sensor is very high, and price is high, limits the popularization of this technology.
Microwave remote sensing method principle is the launched microwave radiation in ocean own, and the microwave signal that sea oil reservoir meeting transmitting ratio water body itself is stronger, signal can change with the thickness of oil reservoir, therefore can be used in theory measuring oil film thickness.But the spatial resolution of microwave remote sensor is lower, and is subject to cyclic effects, an a bright signal often more than corresponding oil film thickness, its practical being also difficult to realizes.
