英文摘要	In the event of an offshore oil spill accident, timely acquisition of the oil spill area and volume is of great significance for scientific decision-making and emergency responses. The remote sensing acquisition breakthrough point pertaining to oil spill volume is the determination of oil film thickness (OFT). Several rules have been identified based on the empirical relationships between the oil film's normalized radar cross section (NRCS) obtained from C-band field experiments and the inversion of the OFT retrieved from synchronous optical images. Inversion formulas suitable for different OFT ranges under certain conditions are established. Following experimental data verification, our results show that the correlation coefficient is greater than 0.99, and the root mean square error (RMSE) is less than 15 mu m. The damping ratio (DR) of the spaceborne synthetic aperture radar (SAR) image is used as a bridge to establish the correlation between the optical OFT and the SAR-inverted OFT. The pixels of the SAR image are classified and substituted into different inversion formulas to obtain the OFT distributions in the SAR images. Then, the OFT distributions of the SAR-inverted and optical images are compared and evaluated. It is found that the OFT of the SAR image can explain the spatial distribution of the oil film. This study provides a new idea for spaceborne SAR OFT inversion.
