The application refers to a radar transceiver comprising a set of transmitters (TX1,..,TXn) for transmitting radar chirps to targets, a set of receivers (RX1,...,RXn) for receiving reflected chirps from the targets, a timing engine (1) coupled to the set of transmitters (TX1,..,TXn) and to the set of receivers (RX1,...,RXn) and adapted to transmit a first set of control signals to the set of transmitters (TX1,..,TXn) and to the set of receivers (RX1,...,RXn). The timing engine (1) is further coupled to a computing unit (4). The timing engine (1) is adapted to receive a second set of control signals generated by the computing unit (4) and transmitted via a bus. The radar transceiver further comprises a sweep control unit (2) coupled to the timing engine (1) and adapted to receive a first control signal and a second control signal from the timing engine (1), the first control signal indicating a precise start time of a chirp and the second control signal indicating a precise reset time for resetting the chirp. The sweep control unit (2) is further coupled to a controlled Phase Locked Loop (PLL) (3) adapted to generate a local oscillator (Master LO) signal which is adapted to be inputted to both each member of the set of transmitters (TX1,..,TXn) and each member of the set of receivers (RX1,...,RXn). |
