摘要 在首先给出超宽带合成孔径雷达 ( UWB-SAR)抑制射频干扰 ( RFI)问题的参数化模型基础上 ,从信号参数估计出发 ,具体推导了实信号下 RELAX算法的计算公式。针对 RFI的复杂性 ,提出了一种逐级RELAX算法 ( GRELAX)。基于仿真和实测数据的实验结果表明 :GRELAX算法能够有效地抑制 RFI。 We first present the parametric model of Radio Frequency Interference (RFI) suppression in Ultra WideBand Synthetic Aperture Radar (UWB SAR). Starting from the problem of signal parameter estimation, we deduce in detail the computation formula of RELAX algorithm for real valued signal. As to the complexity of RFI, a Gradual RELAX (GRELAX) algorithm is proposed. Experiments with synthesized and raw RFI data demonstrate the efficiency of GRELAX in RFI suppression and its high processing speed.
