A radar system is provided that includes a first radar transceiver integrated circuit (IC) including transmission signal generation circuitry operable to generate a continuous wave signal and a first transmit channel coupled to the transmission generation circuitry to receive the continuous wave signal and transmit a test signal based on the continuous wave signal, and a second radar transceiver IC including a first receive channel coupled to an output of the first transmit channel of the first radar transceiver IC via a loopback path to receive the test signal from first the transmit channel, the second radar transceiver IC operable to measure phase response in the test signal.

Multi-chip transceiver testing in a radar system

Methods for monitoring of performance parameters of one or more receive channels and/or one or more transmit channels of a radar system-on-a-chip (SOC) are provided. The radar SOC may include a loopback path coupling at least one transmit channel to at least one receive channel to provide a test signal from the at least one transmit channel to the at least one receive channel when the radar SOC is operated in test mode. In some embodiments, the loopback path includes a combiner coupled to each of one or more transmit channels, a splitter coupled to each of one or more receive channels, and a single wire coupling an output of the combiner to an input of the splitter.
