Multipath clutter cancellation and tracking algorithms for passive radars

We demonstrate the ability of a passive radar system to monitor a large area of interest by applying advanced multipath clutter cancellation algorithm, spatial beamforming and tracking techniques. The mitigation of clutter disturbance and a two stage beamforming method facilitate real time tracking of small to moderate size targets in real Cartesian domain. The results have been validated through a real data acquisition campaign performed using an eleven element array antenna based passive radar developed at FHR Institute in Germany.
