摘　　要：SAR(Synthetic Aperture Radar)信号处理窄带干扰抑制技术是SAR抗干扰技术的重要内容。对3种UWB-SAR(Ultra-W ideBand Synthetic Aperture Radar)窄带干扰抑制方法———陷波滤波法、AR模型参数化干扰抑制法以及小波包分析自适应干扰抑制法进行了分析,利用自行开发的成像软件,对SAR理想点目标和实录数据进行干扰抑制仿真实验,从定性和定量的角度对3种方法的干扰抑制效果作了比较。The narrow band interference suppression by the signal processing method is an important part in the SAR anti-jamming technique. Three methods of narrow band interference suppression in UWB-SAR （Ultra-Wide Band Synthetic Aperture）are analyzed, which are notch filtering, parameterized filtering based on AR model, adaptive interference suppression based on wavelet pack analysis. And the interference suppression experiments of idealized point targets and actual SAR data are made using the simulation software developed by us. From the qualitative and quantitative aspects, the interference suppression effects of the three methods are compared with each other.
