| 摘 要： | 工作在短波频段的高频地波雷达，受到大量射频(radio frequency, RF)信号的干扰，严重影响了对目标的正常检测和参数估计。根据RF干扰经混频和低通滤波后的时域输出特性，提出了基于压缩感知理论的RF干扰抑制方法。该方法能够利用少量未被干扰的采样数据对目标的距离参数做出精确估计。理论分析和仿真结果表明，该方法在RF干扰较少和密集的情况下都能保持良好的干扰抑制效果和对目标参数的准确估计。

| Abstract: | High frequency surface wave radar works in short wave band, and there are lots of radio frequency (RF) interferences, which cannot be eliminated completely and affects the estimation of targets. According to the time characteristics of interference after mixing and lowpass-filter, a method of RF interference suppression based on compressed sensing is proposed. This method can estimate the target range exactly with a few of sample data, which cannot to be interfered. Theoretic analysis and experimental results show the validity of the proposed method. |
