Abstract: Six decades have passed since the first radar detection attempt revealed the mechanism of HF radio waves scattered by ocean surface waves. The combination of radio science theories, radar techniques and physical oceanography principles prompts the development of radio oceanography which is now an important branch in marine science study and an efficient wide area maritime surveillance tool. After summarizing oceanographic radar development and its current application state, this paper introduces the key techniques applied in oceanographic radar and analyzes their application scenarios. China has achieved many progresses in oceanographic radar techniques during the past three decades, while the data assimilation and application of radar data are still left behind compared with advanced countries. Several oceanographic radar techniques are proposed to be the projects with higher priority in the 13thFive-Year Plan period, such as the HF sky-surface wave hybrid radar network techniques, the high-resolution HF/VHF radar on floating/moving platform, novel technique microwave radar, and the data management and assimilation techniques of oceanographic radars.
