In this work, for the first time, a 5G/mm-Wave harmonic frequency modulated continuous wave (FMCW) radar with dual Rotman lens-based millimeter identification (mmID) ranging system is proposed enabling ultralong range highly accurate localization future localized sensing cyberphysical systems (CPSs). A detailed characterization of fully-passive mmID presented an estimated maximum cross section (RCS) −35.8 dBsm and 10 dB beamwidth ±50°. The fully overcomes high-gain tradeoff seen in typical designs robust, ultralong-range detectability. link budget analysis current proof-of-concept (PoC) equivalent isotropic radiated power (EIRP) 75 dBm reading ranges excess 8 km are envisioned. addition, provides at long bounded error 17 cm up to 46 m from radar. Furthermore, capitalizes on sensitive phase information ultrafine 0.4 mm m. Thus, presents fully-passive, long-range CPSs.
