Abstract
High Frequency Surface Wave Radar (HFSWR) has been widely used for remote sensing and maritime target detection. However, the HFSWR system contains a huge antenna array for accurate angle measurement. Miniaturization of antenna array has been one of the most urgent problems in this field. Applying the Multiple-Input Multiple-Output (MIMO) technology to radar can effectively improve the angle estimation accuracy in the case of small aperture through virtual channels. Hence, the superiority of MIMO contributes to improve the performance of HFSWR system. Slow-time MIMO is a special form of MIMO radar through Doppler diversity, and it can operate at same time and same frequency. This paper introduces the experiment of slow-time MIMO in HFSWR system in recent days. The results validated on real data can prove the benefit of MIMO technology in angle estimating, and we analyze the specific impact of sea clutter, ionospheric clutter and radio interference for Slow-time MIMO HFSWR.
