Patent ID: 7737880

Claim:
A radar system located on a vehicle, the system comprising: a central processor; a plurality of sensor transceivers located at various points around the vehicle, the plurality of sensor transceivers being in signal communication with the central processor, the plurality of sensor transceivers comprising: at least one antenna; receive electronics in signal communication with the at least one antenna and the processor; and transmit electronics in signal communication with the at least one antenna, the transmit electronics configured to output radar signals via the at least one antenna, the transmit electronics comprising: a voltage controlled oscillator (VCO); a dielectric resonator oscillator (DRO); a phase locked loop (PLL) component; a direct digital synthesizer (DDS); a mixer configured to combine a signal produced by the DRO with a millimeter wavelength signal produced by the VCO; and a low pass filter configured to filter a high frequency component of the output of the mixer and apply the remaining low frequency component to the PLL component, wherein the receive electronics are configured to receive from the at least one antenna any radar reflections corresponding to the outputted radar signals and to send signals associated with the radar reflections to the processor, wherein the central processor is configured to generate output signals based on the signals received from the plurality of sensor transceivers.
