Abstract: This paper investigates a terahertz (THz) interferometer that uses a movable diffraction grating to access otherwise unobservable carrier phase information for bearing angle estimation. It proposes a GPS-like signal structure that is specifically tailored to the unique challenges and limitations of both the THz hardware and the moving diffraction grating, making multi-access communication and navigation possible. A frequency-matching scheme is proposed to minimize the likelihood of missed communications. Probabilistic analysis indicates that the proposed signal structure and frequency-matching scheme achieve reliable communication and navigation links for aircraft flying in formation.
