摘要In this paper, we compared the normalized radar cross section in the cases of oil spill, biogenic slicks, and clean sea areas with image samples made from 11-pixel NRCS average, and determined their thresholds of the NRCS of the synthetic aperture radar. The results show that the thresholds of oil and biogenic slicks exhibit good consistency with the corresponding synthetic aperture radar images. In addition, we used the normalized radar cross section of clean water from adjacent patches of oil or biogenic slicks areas to replace that of oil or biogenic slicks areas, and retrieve wind field by CMOD5.n and compare wind velocity mending of oil and biogenic slicks areas with Weather Research and Forecasting modeled data, from which the root mean squares of wind speed (wind direction) inversion are 0.89 m/s (20.26A degrees) and 0.88 m/s (7.07A degrees), respectively. Therefore, after the occurrence of oil spill or biogenic slicks, the real wind field could be repaired using the method we introduced in this paper. We believe that this method could improve the accuracy in assessment of a real wind field on medium and small scales at sea, and enhance effectively the monitoring works on similar oil or biogenic slicks incidents at sea surface.; In this paper, we compared the normalized radar cross section in the cases of oil spill, biogenic slicks, and clean sea areas with image samples made from 11-pixel NRCS average, and determined their thresholds of the NRCS of the synthetic aperture radar.
