GPSAR的一种特征子空间滤波干扰抑制方法

An Interference Suppression Approach for GPSAR Using Eigen-Subspace Filtering

详细分析了轨道地表穿透合成孔径雷达(Rail-GPSAR)所受到的各种干扰的特性,发现特征子空间滤波法能够有效地同时滤除射频干扰(RFI)和耦合杂波。实验结果表明,抑制干扰的效果明显,达到了预期的目的。

This paper analyses the characteristics of the clutter of a rail Ground Penetrating Synthetic Aperture Radar（ Rail -GPSAR）. An approach for clutter suppression is proposed, which uses eigen - subspace based filtering to degrade both the Radio Frequency Interference （RFI） and the coupling clutter. The resuits show that the proposed approach can suppress the clutter effectively.
