Overview
The R-GAGE sensor emits high-frequency radio waves from an internal antenna, which
forms a well-defined beam. Some of this emitted energy is reflected back to the receiving
antenna. Signal processing electronics determine the distance from the sensor to the
vehicle based on the time delay of the return signal. The sensor is configured to operate
like a retroreflective photoelectric sensor. See Figure 3.
