Abstract Based on radar backscattering turbulence model of ocean surface caused by wave-current interaction, For weak ocean current , it simplifies the model and calculates the radar backscattering coefficient ' s turbulence caused by weak ocean current . It analyzes the relationships between the results and current field, current amplitude, wind speed, wave-current angle, radar wave band and radar incidence angle.Then it gives the turbulence characteristics. Thus this paper will provide valuable help for studying the detecting capability of radar for ocean surface current .
