Abstract :
Some results of analysis conclude that the internal wave can affect the sea wind-generated wave crucially, so that the spectrum accounts for the interactions between the two kinds of sea water masses. These backscattering coefficients of the internal wave sea surface of the South China Sea are calculated using some existing models and the results are compared with the calculations of SIR-C/X-SAR data. Different results among the radar bands exist and are affected by sea surface roughness. The ocean wave spectrum is derived from the X-SAR image. Finally, we point out that the tidal current is the main factor that causes the internal waves.
