摘要

非相干散射雷达(ISR)通过探测自由电子的汤姆逊散射回波反演电离层参数，被认为是地面观测电离层最有效的仪器。事实上，在回波数据中，高度100km左右通常存在严重的地面杂波。利用曲靖非相干散射雷达数据，引入脉冲减法处理地杂波。结果表明，该脉冲减法能较好地抑制地杂波。

Ground clutter suppression: Preliminary analysis of Qujing incoherent scatter radar

Incoherent scatter radar (ISR) detects the Thomson scatter echo of free electrons to inverse ionosphere parameters and is thought as the most powerful instrument to observe the ionosphere on the ground. In fact there are usually severe ground clutters around altitude 100km in the echo data. This paper introduces pulse subtraction to deal with ground clutter by using the Qujing incoherent scatter radar data. The results show that this pulse subtraction suppresses ground clutter well.
