Claim 7:
8. A method to test a radar circuit including an oscillator, a transmitter, and multiple receivers, the method comprising:
generating, by the oscillator, a frequency modulated continuous waveform (FMCW);
modulating, by the transmitter, the FMCW to produce a modulated FMCW;
transmitting, by the transmitter, the modulated FMCW to a transmission network;
processing, by the transmission network, the modulated FMCW to generate an internal signal;
outputting, by the transmission network, a receiver input signal for each of the multiple receivers based on the internal signal;
outputting, by each of the multiple receivers, a corresponding output signal based on the corresponding receiver input signal; and
comparing each output signal to an expected output signal for the corresponding receiver.
