Query: Through-Wall Person Localization Using Transceivers in Motion   We develop novel methods for device-free localization (DFL) using
transceivers in motion. Such localization technologies are useful in various
cross-layer applications/protocols including those that are related to security
situations where it is important to know the presence and position of an
unauthorized person; in monitoring the daily activities of elderly or special
needs individuals; or in emergency situations when police or firefighters can
use the locations of people inside of a building in order to save lives. We
propose that transceivers mounted on autonomous vehicles could be both quickly
deployed and kept moving to ``sweep'' an area for changes in the channel that
would indicate the location of moving people and objects. The challenge is that
changes to channel measurements are introduced both by changes in the
environment and from motion of the transceivers. In this paper, we demonstrate
a method to detect human movement despite transceiver motion using
ultra-wideband impulse radar (UWB-IR) transceivers. The measurements reliably
detect a person's presence on a link line despite small-scale fading. We
explore via multiple experiments the ability of mobile UWB-IR transceivers,
moving outside of the walls of a room, to measure many lines crossing through
the room and accurately locate a person inside within 0.25 m average error.
