Abstract

Abstract

On the basis of the SAR data, on the backscattering coefficient computation’s foundation, the marine oil spill monitoring and surveying parametric analysis have been carried out from wave band, polarization mode, incidence angle.The result shows that based on the SAR marine oil spill monitor, from the wave band analysis, X wave band and C wave band are more suitable to monitoring marine oil spill comparing with L wave band; from the polarization mode analysis, VV polarization is more suitable to monitoring marine oil spill comparing with HH and HV polarization; from the incidence angle analysis, when the critical value of oil spill and seawater is conparted, after testing many times, doubtful oil spill located at the far incidence angle separates not easily with the seawater;doubtful oil spill of the relatively near incidence angle separates easily with the seawater.The ALOS PALSAR inages incidence angle is approximately 23°~43°, the COSMO-SlyMed incidence angle is 32°~35°, the incidence angle which separates the seawater from the oil spill is approximately easy 23°~35°.
