摘要 针对高频地波雷达射频干扰抑制问题,研究基于独立分量分析(ICA)的单通道干扰分离方法,方法突破了常规ICA无法用于单接收通道下信号分离的条件限制,分析了高频地波雷达目标回波与射频干扰的周期性,并根据信号周期性与高频地波雷达相干积累时间长的特点,运用ICA方法实现了目标回波与射频干扰的分离,仿真实验与理论分析证明了该方法的有效性。 To suppress the radio frequency(RF) interference in the high frequency surface wave radar(HFSWR), a new method based on independent component a- nalysis (ICA) in the single receive channel is proposed. Based on the periodicity of signal and the long time of coherent integration in HFSWR, the target signal and RF interference can be separated by ICA. Experimental results show the validity of the proposed method.
