1. A radar system for providing position information to a mobile unit, the radar system comprising:
a receiving interface which is adapted to receive radio frequency (RF) signals;
a processing unit which is adapted to process received RF signals and to determine an occupation of a predetermined time-frequency space by the received RF signals;
a transmitting interface adapted to transmit information on an intention of the radar system to occupy a specific portion of the predetermined time-frequency space; and
a plurality of beacon units adapted to provide position information of the radar system on the specific portion in the predetermined time-frequency space, when it is determined that the specific portion of the predetermined time-frequency space is not occupied, and wherein
the plurality of beacon units is adapted to transmit, on the specific portion in the predetermined time-frequency space, ranging signals based on which the mobile unit can compute its 3D position.
