Repair Wind Field of Oil Spill Regional Using SAR Data
In this paper, we compared the normalized radar cross section (NRCS) of the synthetic aperture radar in the cases of
oil spill and clean sea areas with image samples and determined their thresholds of the NRCS of SAR. we used the
NRCS of clean water from the adjacent patches spill area to replace NRCS of oil spill area and retrieval wind field
by CMOD5.N and comparison of wind velocity mending of oil spill with Model data the root mean square of wind
speed and wind direction inversion are 0.89m/s and 20.26°satisfactory results, respectively. Therefore, after the
occurrence not large scale oil spill, the real wind field could be restored by this method.
