IEEE 802.22 Passive Radars: Multistatic Detection and Velocity Profiler

This work focuses on a passive coherent location (PCL) system that exploits the signals emitted by IEEE 802.22 devices, referred hereafter as a white-space PCL (WS-PCL) system. To cope with the very low transmitted equivalent isotropically radiated power of the IEEE 802.22 emitters, we focus on the design of a WS-PCL system that exploits all the useful signals, emitted from both the base station and customer-premises equipment, received in each frame. In this work, we study the feasibility of a WS-PCL system by deriving the receiver operating characteristic and defining the multistatic velocity profiling algorithm for the estimation of the target velocity vector. The performance of the proposed receiver is compared to that of a WS-PCL system that exploits only the signal emitted by the base station.
