Abstract

A method of localizing a TPMS sensor module includes transmitting, by the TPMS sensor module, a TPMS signal; and localizing, by a localization module, the TPMS sensor module based on receiving the TPMS signal at a phase array antenna including a plurality of reception antennas each configured to receive the TPMS signal at a different phase, where the plurality of reception antennas include a reference reception antenna and at least one additional reception antenna. Localizing the TPMS sensor module includes measuring a reference phase of the TPMS signal received at the reference reception antenna, measuring a respective shifted phase of the TPMS signal received at each of the at least one additional reception antenna, determining a respective phase shift between the reference phase and each respective shifted phase, and determining a location of the TPMS sensor module based on each determined respective phase shift corresponding to the TPMS signal.
