A MODULAR VEHICLE RADAR
A vehicle radar system ( 3 ) including at least one group of at least two transceiver arrangements ( 7 a, 7 b ) that are arranged to generate a respective radar signal ( 4 a, 4 b ), and to receive reflected signals ( 5 a, 5 b ) where the transmitted radar signals ( 4 a, 4 b ) have been reflected by one or more objects ( 6 ). Each such group of transceiver arrangements ( 7 a, 7 b ) is connected to a separate common control unit ( 13 ) via a corresponding serial link ( 22 a, 22 b ). The common control unit ( 13 ) includes a DSP (Digital Signal Processor) arrangement ( 12 ) and a control unit ( 32 ).
1 . A vehicle radar system comprising, a group of at least two transceiver arrangements that are arranged to generate a respective radar signal, and to receive a reflected signal where the transmitted radar signal is reflected by one or more objects, each of the transceiver arrangements of the group is connected to a separate common control unit by a corresponding serial link, where the common control unit comprises a digital signal processor arrangement and a control unit.
2 . The vehicle radar system according to claim 1 , further comprising, the serial link is in the form of a shielded twisted wire pair or a coaxial cable.
3 . The vehicle radar system according to claim 1 , wherein the serial link comprises an FPD-Link III SerDes with a CSI-2 interface.
4 . The vehicle radar system according to claim 1 , further comprising, the common control unit is in the form of a System-On-Chip, or a micro-controller DSP combination which is arranged to handle radar signal processing and vehicle data processing.
5 . The vehicle radar system according to claim 1 , further comprising, that the common control unit is in the form of a radar control unit, or an advanced driver assistance system and electronic control unit.
6 . The vehicle radar system according to claim 1 , further comprising, the common control unit is connected to one or more other components in a vehicle via a vehicle bus.
7 . The vehicle radar system according to claim 1 , further comprising, the radar signal is in the form of a frequency modulated continuous wave chirp signal where the chirp signal comprises a corresponding plurality of frequency ramps, and where the frequency ramps run between a first frequency and a second frequency.
8 . The vehicle radar system according to claim 1 , further comprising, the radar system is arranged to provide an input to a safety control unit that is arranged to control a safety system, where the radar system, the safety control unit and the safety means system are comprised in a vehicle.
