The scattering fields of 2D sea fractal surface with finite conductivity illuminated by ellipse polarization wave in Cartesian coordinate system have been evaluated in part one. We derive here the relation expression between scattering fields and d illumination fields with 3/spl times/3 matrix in local coordinate system. The radar cross section (RCS) on different polarization is obtained and numerically simulated. It shows that the results of our scattering model are in agreement with those of other literatures for some special case. We get some conclusions: (1) valued of radar cross sections of cross polarization (VH and HV) are less than those of co-polarization (VV and HH) but cannot be neglected; (2) when the incidence angle /spl theta//sub 1/, and the scattering angle /spl theta//sub 2/ are determined, the angle of the scattering plane out of the illuminating plane /spl theta//sub 3/ varies from 0/spl deg/ to 180/spl deg/, different relations among /spl theta//sub 1/, /spl theta//sub 2/ and /spl theta//sub 3/ in different relationships between /spl sigma//sub vs,vt//sup 0/, /spl sigma//sub h/spl delta//,h/sub i//sup 0/ and /spl sigma//sub v/spl delta//,h/sub i//sup 0/, /spl sigma//sub h/spl delta//,v/sub i//sup 0/ are derived, we can use these inequalities to predict the critical angle /spl theta//sub 3/ where the relation between RCS of VV and HH,VH and HV polarization will exchange, respectively; (3) the effects of depolarization can be neglected though we derived the expressions for them.
