Abstract

A radar system (300) and a method of operating the radar system is disclosed, the radar system (300) comprising: a first IC (310), arranged to receive a reference clock signal (380) and configurable to generate a common local oscillator signal (400) based on the reference clock signal (380); a second IC (320), arranged to receive the common local oscillator signal (400) from the first IC (310); and a controller (350), adapted to detect a fault in the first IC (310), and configured, upon detection of a fault in the first IC (310), to send at least one signal to the second IC (320) for reconfiguring the second IC (320) from a slave mode to a master mode; wherein, when operating in the slave mode, the second IC (320) is configured to use the common local oscillator signal (400) generated by the first IC (310), and, when operating in the master mode, said second IC (320) is configured to use an internally-generated local oscillator signal. The second IC (310) may be configured to receive the reference clock signal (380), wherein the internally-generated local oscillator signal is based on the reference clock signal (380).
