摘　　要：高频地波超视距雷达能够完成视距外的海洋环境监测以及目标检测与跟踪,但是电离层杂波的存在会使高频地波超视距雷达的目标检测和目标跟踪等性能严重降低,特别是当目标方位与电离层杂波方位一致或相近时,目标检测难度大大增加。利用实测数据分析了电离层杂波的相关性,根据电离层杂波的特点,提出了基于空时自适应处理方法抑制电离层杂波,并通过实测数据,验证了方法的有效性。The high frequency surface wave radar （HFSWR） can accomplish the marine environmental mo- nitoring, targets detecting and tracking over the horizon. Due to the ionospheric clutter, the performance is re- duced 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.
