Patent ID: 11513190

Abstract:
Methods, apparatus, systems and articles of manufacture are disclosed to test RADAR integrated circuits. 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, the controller to cause the LO to generate a frequency modulated continuous waveform (FMCW), cause the transmitter to modulate the FMCW as a modulated FMCW, cause the transmitter to transmit the modulated FMCW via the transmission network and the receiver to obtain a received FMCW from the transmission network, and in response to obtaining the received FMCW from the receiver, generate a performance characteristic of the radar circuit based on the received FMCW.
