An Interference Suppression Approach for GPSAR Using Eigen-Subspace Filtering |
|
() |
Abstract: |
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 results show that the proposed approach can suppress the clutter effectively. |
Key words: ground penetrating synthetic aperture radar(GPSAR),eigen-subspace filtering,interference suppression |
