Abstract:

The high frequency surface wave radar (HFSWR) can accomplish the marine environmental monitoring, targets detecting and tracking over the horizon. Due to the ionospheric clutter, the performance is reduced seriously. Especially, the detection of the target is more difficult when the direction of arrival (DOA) of the target is approximately with the ionospheric clutter. The correlation of the ionospheric clutter is analyzed by utilizing the measured data. According to these characteristics,  a method is proposed to suppress the ionospheric clutter based on space time adaptive processing (STAP)， and it is proved by utilizing the measured data.
