Abstract
A system and method reconfiguring an antenna for reducing and/or eliminating the effects of multipath on a phase-based measurement system. The method includes steering an antenna unit into a first direction to cause the antenna unit to generate a first constant tone (CT) signal based on a plurality of multipath signals. The method includes performing a phase measurement on the first CT signal to generate a first phase measurement value. The method includes steering the antenna unit into a second direction to cause the antenna unit to generate a second CT signal based on the plurality of multipath signals. The method includes performing a phase measurement on the second CT signal to generate a second phase measurement value. The method includes determining a change in multipath interference at the antenna unit among the plurality of multipath signals. The method includes re-steering the antenna unit into the first direction.
