Wide band noise interference suppression for SAR with dechirping and eigensubspace filtering

It is necessary to enhance the anti-jamming capability of Synthetic Aperture Radar (SAR) for ensuring its imaging performance. A new approach to suppress wide band noise interference (WBNI) based on dechirping and eigensubspace filtering was proposed in this essay, and computer simulations were performed. All results prove that this approach can effectively suppress WBNI with negligible signal distortion under the condition that the Jamming-to-Signal Ratio (JSR) is 5dB smaller than pulse compression gain.
