Abstract
The disclosure relates to a radar system comprising multiple synchronized transceivers. Example embodiments include a radar system () comprising: a plurality of radar transceiver units (-), each configured to operate according to a low frequency clock signal (), and configured to generate an intermediate frequency signal () and a modulated high frequency signal () for transmitting and receiving radar signals; and a microcontroller unit () configured to provide control signals to each transceiver unit (-) to synchronize operation thereof, wherein each radar transceiver unit (-) is configured to provide received radar data (RX) and a monitoring signal (-) to the microcontroller unit (), the monitoring signal (-) derived by frequency dividing and combining the modulated high frequency signal and intermediate frequency signal, and wherein the microcontroller unit () is configured to derive and compensate for phase and frequency differences between the received radar data (RX) from each transceiver (-) based on the monitoring signals (-) provided by each transceiver unit (-).
