Claim 14:
15. An apparatus to test a radar circuit that includes an oscillator, a transmitter, and a receiver, the apparatus comprising:
a modulator manager configured to:
cause the oscillator 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 via a transmission network to obtain an output signal from the transmission network;
cause the receiver output a receiver FMCW in response to the output signal; and
a signal analyzer configured to compare the receiver FMCW with an expected FMCW for the receiver with respect to a performance characteristic of the radar circuit.
