A modified EMD method for detecting and mitigating narrow-band RFI in SAR data

本文提出了一种改进的 EMD 方法来解决含干扰 SAR 数据 RFI 抑制过程有用信号损失这一问题。首先，通过相对能量比检测回波的干扰;其次，通过 EMD 将含有射频干扰的回波分解成多个 IMF。这些 IMF 通过 STFT 转换成时频域，然后通过鲁棒的双 k-均值算法筛选出与 RFI 相对应的 IMF。最后，利用鲁棒 OTSU 算法对时频域的 RFI 进行定位，并通过陷波运算进行抑制。利用仿真的射频干扰对真实 SAR 数据进行实验，结果表明了该方法的有效性和优越性。[pdf, SCI, EI, IF=2.3000, CAS-G4, JCR-Q3]
