DOI: 10.1109/lsp.2019.2938632
Abstract: The resolution of the integer phase ambiguity among a group of spatially separated sensors is considered, where the smallest inter-sensor spacing exceeds half wavelength ($\lambda /2$) of a single-frequency signal. The sufficient condition that the… read more here.

DOI: 10.1109/tsp.2022.3146023
Abstract: The problem of range estimation based on noisy measurements with phase ambiguity can be solved using signals across multiple frequencies by existing algorithms based on either the Chinese Remainder Theorem or lattice theory. The performances… read more here.
