Simultaneous localization and data-interrogation using a 24-GHz modulated-reflector FMCW radar system

Abstract

In this paper, the integration of a communication link for a modulated-reflector radar is presented. This kind of radar system is intended to determine the position of multiple semi-passive backscatter reflector nodes, designed to be mounted on different objects of interest. A method to transport information from these objects back to the radar-basestation is sketched, using the available hardware-resources of the nodes. In addition a technique minimizing the influence of this communication link on the localization capability of the system is presented and validated by measurements.
