Abstract
This paper considers target localization from ambient radio frequency (RF) signals transmitted by the target. We consider a new practical scenario with an array of asynchronous receivers deployed at arbitrary locations, and present an algorithm that jointly locates the target and self-locates the receivers. The approach exploits time-difference-of-arrival (TDoA) between multipath components (multipath TDoA) at each receiver. We derive lower bounds for the localization errors of all the target and receiver locations. The performance is verified numerically and demonstrated experimentally with a hardware implementation that was tested in an anechoic chamber using passive IEEE 802.11ac receivers. We have shown that sub-meter level accuracy can be achieved using 6 static receivers.
