外文摘要：Inversion model of petroleum-contaminated water absorption coefficient a(λ0) at reference wavelength (for example, 440nm) was built based on the relation between the remote sensing reflectance and the sensitive wavelength of water absorption coefficient. On this basis, according to remote sensing reflectance, the normalized unit absorption coefficient was obtained with measured oily sewage absorption coefficient data and aoil(440) was calculated, further combined with the known S value, figured out aoil(λ0) for each band. Finally, the corresponding oil concentration was determined by least squares method with relation between oil concentration and unit absorption coefficient as the absorption coefficient formula. This study provided a method of retrieving oil content in petroleum- contaminated water using inherent optical properties. ? 2019 IEEE.
