Abstract:

Distributed, passive radar systems receive signals reflected by radar targets that were transmitted by other systems. The signals received by the passive radars may be processed individually at each receiver node, or the signals from the different nodes may be combined and processed coherently. We implemented both methods in a coaxial-cable testbed. Both methods gave similar results, but coherent processing may give better results at low signal-to-noise ratios.
