Classification: CPC G | IPC G

Claim 0:
1. A radar circuit comprising:
a local oscillator (LO);
a transmitter coupled to the LO and configured to be coupled to a transmission network;
a receiver configured to be coupled to the transmission network; and
a controller coupled to the LO, the transmitter, and the receiver, wherein the controller is configured to:
cause the LO to generate a frequency modulated continuous waveform (FMCW);
cause the transmitter to modulate the FMCW to output a modulated FMCW;
cause the transmitter to transmit the modulated FMCW to the transmission network to obtain an output signal from the transmission network; and
cause the receiver to output a receiver FMCW in response to the output signal;
wherein the controller is further configured to compare the receiver FMCW with an expected FMCW for the receiver with respect to a performance characteristic of the radar circuit.
