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...
Path diversity provided by overlay networks brings about possibilities to choose alternate optimal path against default one. In this paper, we present a routing mechanism which chooses path based on a composite metric, whose comprising metrics are determined by active probing measurements on the overlay network in a real-time fashion.
