Localization and tracking of moving targets with WiFi-based passive radar

This paper investigates the possibility of obtaining localization and tracking of moving targets by exploiting a passive radar system based on WiFi transmissions. Specifically, the exploitation of multiple passive sensors is considered which allows to collect a set of range/Doppler/DoA measures for a given target when observed at different bistatic geometries. Different target localization strategies are investigated based on proper subsets of the available measures. Experimental results are shown which have been obtained by means of a passive radar prototype developed and fielded at the DIET Dept. - Sapienza University of Rome. This will contribute to demonstrate the fruitful application of the passive radar concept for short range surveillance. © 2012 IEEE.
