Fig, 6. Ratios of mean Doppler frequency (w) to Bragg frequency 

 wgfor the wave-facet interaction model at windspeed 

 U = 20 m/s. The indices i, 2, 3, 4 refer to P, L, C and 

 X bands, respectively. The computations include ternns up 

 to order q| in the expansion (11). To this approximation, 

 the cross polarised case yields ( w) = cog.
