【Abstract】 On the basis of D.E.Barrick′s sea echo section equations, on ocean wave scattering coefficient model in relation to sea state is studied,and sea clutter power spectral density model based on sea clutter characteristics of high frequency(HF) radar is established.Then both ocean wave scattering coefficient simulation and sea clutter power spectral density numerical simulation are implemented.Results of simulation provide a theory basis and enhanced means of analysing HF radar system detection performance,and become an important part of HF radar system simulation.更多还原
