Summary: Target Localization Using Radar Sensor Networks
Target localization in WSNs (Wireless Sensor Networks) has been an active research area due
to its importance and wide range of applications. Most of the proposals so far, however, have
focused on cooperative targets that in one way or another work with the localization
infrastructure. For example, mobile targets can emit RF or acoustic signals either on purpose
(ActiveBadges) or by their nature (e.g., bird chirps). Instead, we focus on localizing
non-cooperative targets using active sensors. Specifically, we use a network of mono-static
low-power, pulsed, Dopper radars that independently estimate the target's Doppler velocity with
respect to each radar. These measurements are then used to estimate the target's location and
true velocity using an Extended Kalman filter. We have built a prototype of this system using
TelosB motes and BumbleBee radars.
Overview
Target localization in WSN(Wireless Sensor Networks) has been an active research area due to
its importance and wide range of applications. Most of the proposals so far, however, have
focused on cooperative systems that requires targets to cooperate with the localization
infrastructure. Instead, we consider a non-cooperative approach requiring zero help from the
targets. Specifically, we use Radar Sensor Network (RSN), a group of Pulsed Doppler radars
interfacing with Tmotes for target tracking.
