Abstract
A microwave position sensing system includes a plurality of target components that each move between multiple positions. A microwave generator produces a microwave frequency signal. A divider receives the microwave frequency signal and splits the microwave frequency signal into a plurality of position sensing signals. The position sensing signals are respectively sent to the plurality of target components to determine a position of each of the target components. Each position sensing signal may also be calibrated. In one example, first and second frequencies are transmitted through a common wave guide. The first frequency is reflected prior to reaching the target component to produce a calibration signal. The second signal, which is used to detect the position of the target component, is calibrated using the first frequency.
