1. An apparatus for determining the position of an object in three-dimensional space, the apparatus, comprising:
an antenna structure, wherein the antenna structure has an L-, U- or T-shaped structure and is mounted on a radiator grille of the front radiator of a vehicle, wherein the antenna structure comprises transmit antennas and receive antennas; and
an analog to digital (ADC) converter that samples signals received by the receive antennas to form sampled signals, wherein the signals received by the receive antennas include codes that respectively correspond to the transmit antennas; and
a decoder that decodes the sampled signals to form a virtual antenna array for two-dimensional horizontal and vertical beam scanning;
wherein the virtual antenna array corresponds at least in part to a ventilation opening of the radiator grille of the front radiator,
wherein the transmit antennas are configured to simultaneously emit transmitted signals, and further wherein the apparatus employs both frequency modulation and phase modulation in connection with emitting the transmitted signals.
