Abstract

In this paper, we present a concept for wireless local positioning with
multiple backscatter transponders based on the switched-injection locked
oscillator (SILO). It allows reliable localization and ego-motion
estimation of autonomous robots in indoor and outdoor environments. We
derive the range-doppler spectrum of the beat signal that is induced by a
single transponder in a FMCW radar system. With multiple transponders, a
localization network is created that allows multilateral and
multiangulation based positioning. For an initial evaluation, we built a
miniaturized transponder for the 24 GHz ISM band and proofed the
concept with a straightforward measurement, including two transponders, a
moving ground robot equipped with a FMCW radar system and a laser
tracker reference.
