Claim 4:
5. The radar circuit of claim 1, wherein the receiver is a first receiver, the receiver FMCW is a first receiver FMCW associated with the first receiver, and the expected FMCW is a first expected FMCW associated with the first receiver, the radar circuit further including a second receiver, a second receiver FMCW associated with the second receiver, and a second expected FMCW associated with the second receiver, and wherein:
the output signal of the transmission network is divided via a power divider of the transmission network into a first output signal and a second output signal;
the controller is configured to cause the first receiver to output the first receiver FMCW in response to the first output signal, and to cause the second receiver to output the second receiver FMCW in response to the second output signal; and
the controller is configured to compare the first receiver FMCW with the first expected FMCW and compare the second receiver FMCW with the second expected FMCW;
wherein the performance characteristic includes a characteristic from a group consisting of: a signal to noise ratio of the received FMCW at one of the first receiver or the second receiver, signal power of the received FMCW at one of the first receiver or the second receiver, and gain and phase mismatch between the first receiver and the second receiver.
