A method includes transmitting one or more local transmit radar signals and receiving a plurality of local receive radar signals that corresponds to the one or more local transmit radar signals being reflected or refracted off an object. The method further includes processing the plurality of local receive radar signals to determine a relative position of the object. The method further includes determining whether the object is positioned within a desired detection volume associated with a position of the transmitter section. When the object is positioned within the desired detection volume, further processing the local receive radar signals to determine movement pattern of the object and whether the movement pattern of the object is within a range of plausible movements for the object. When the movement pattern of the object is within a range of plausible movements for the object, tracking movement of the object within the desired detection volume.
