摘      要：This paper presents the compact polarized (CP) pseudo quad-pol parameters for the detection of marine oil spills and segregation of lookalikes using simulated CP SAR data from full-polarized (FP) SAR *** to the CP theory,11 polarized parameters generally used for the detection of oil spills were derived from reconstructed pseudo quad-pol data for both C and L *** addition,the reconstruction performance between C and L bands was also compared by evaluating the reconstruction accuracy of retrieved polarized *** results show that apart from(thv and RH,other polarized parameters of σHH,σVV,H,α,φH-V,r,ρH-V,and γ can be reconstructed with satisfactory accuracy for both C and L ***,C band has a higher reconstruction accuracy than L band,especially for φ***,the effect of reconstruction of polarized parameters on oil spill classification was also evaluated using the maximum likelihood classification (MLC) *** to the evaluation of kappa coefficients and mapping accuracy,it is recommended to use σHH,σVV,H,ρH-V,and γ of the C band CP SAR for marine oil spill classification.
