Abstract

The disclosure relates to a radar system having multiple radar transceiver modules, in which each module has a clock signal that is synchronised with a clock signal generated by a leader transceiver module. Example embodiments include a radar system (400) comprising a plurality of radar transceiver modules (401, 402) mounted to a common PCB (404), the plurality of radar transceiver modules comprising a leader module (401) and one or more follower modules (402), the leader module (401) comprising a first oscillator (403) configured to provide a first clock signal at a first frequency to each follower module (402), each of the leader and follower modules comprising a phase locked loop, PLL, clock signal generator (300), the PLL clock signal generator (300) comprising a divide by n clock divider (304) arranged to output 2n phase shifted clock signals (314) at a third frequency and a multiplexer (306) connected to receive the 2n phase shifted clock signals from the divide by n clock divider (304) and output a third clock signal (308) selected by an input phase select signal (307).
