DOI: 10.1109/jiot.2024.3382046
Abstract: Phase-based 3-D localization of radio-frequency (RF) markers has high sensitivity and accuracy. However, phase measurements suffer from oscillator phase noises, wavelength ambiguities, and multipath interferences. Additionally in the near field, antenna detuning and medium inhomogeneity… read more here.
