Abstract
An apparatus for determining a distance to an object is provided. The apparatus includes a first transceiver configured to transmit a first radio frequency signal. Further, the apparatus includes a second transceiver configured to transmit a second radio frequency signal in response to receiving the first radio frequency signal. The apparatus additionally includes a processing circuit configured to determine the distance to the object based on a transmission time of the first radio frequency signal and a reception time, at the first transceiver, of a reflected component of the second radio frequency signal that is reflected by the object.
