Joint Scatterer Localization and Material Identification Using Radio Access Technology
2021
Cellular network technologies and radar sensing technologies have been
developing in parallel for decades. Instead of developing two individual
technologies, the 6G cellular network is expected to naturally support both
communication and radar functionalities with shared hardware and carrier
frequencies. In this regard, radio access technology (RAT)-based scatterer
localization system is one of the important aspects of joint communication and
sensing system (JCAS) that uses communication signals between transceivers to
determine the location of scatterers in and around the propagation paths. In
this article, we first identify the challenges of RAT-based scatterer
localization system, then present single- and multiple-bounce reflection loss
(RL) simulation results for three common building materials in indoor
environments. We also propose two novel methods to jointly localize and
identify the type of the scatterers in a rich scattering environment.
