Abstract

A radar system (200, 200a) and a method of operating a radar system are described, the radar system (200, 200a) comprising: a plurality of ICs (210, 220), each IC (210, 220) comprising: a respective LO output (212, 222) for selectively outputting a respective LO signal, and a respective LO input (214, 224); and a coupling device (230, 330), the coupling device (230, 330) comprising: a plurality of inputs (232, 234; 341, 342, 351, 352), each input being coupled to the LO output (212, 222) of a respective IC (200, 200a), and a plurality of outputs (236, 238; 363, 364, 373, 374), each output being coupled to the LO input (212, 222) of a respective IC (214, 224); wherein the coupling device (230, 330) is configured such that a LO signal arriving at any one of said plurality of inputs (232, 234; 341, 342, 351, 352) is distributed to each of said plurality of outputs (236, 238; 363, 364, 373, 374). The coupling device (230, 330) may comprise at least one directional coupler.
