Abstract
An automotive spread MIMO-configured radar system has a plurality of transceiver antenna units for transmitting mutually orthogonal radar waves. Each transceiver antenna unit has a plurality of range gates to indicate a range detected by the transceiver antenna unit. At least one specific transceiver antenna unit (TRx) is configured to transmit a reference signal received directly by at least one transceiver antenna unit (TRx) that is separated by an a priori known distance from the specific transceiver antenna unit (TRx). An evaluation and control unit is configured for reading out the plurality of range gates for the transceiver antenna unit (TRx), and, based on the read-out range gate that indicates the received reference signal and based on the a priori known distance, for synchronizing the specific transceiver antenna unit (TRx) and the transceiver antenna unit (TRx) that received the reference signal and/or for correcting a measured Doppler shift.
