Abstract :
The authors have investigated the second order scattering theory for HF scattering by the sea surface. Second order scattering is caused primary by forced waves which satisfy the Bragg condition. When ocean waves develop the theory seems to be invalid; the authors realized it was valid from observational data. The authors have also estimated wave parameters. Wave height and period can be estimated, but it is difficult to estimate wave direction
