Abstract: A method for phase-conjugate target emulation for testing a DSB FMCW radar includes selecting a proxy transponder from an array of frequency-shifting transponders to transmit an emulated target radar signal to a radar DUT. The proxy transponder is located at a mirror image location with respect to a desired DoA of a signal from an emulated radar target. The method further includes receiving a radar signal from the radar DUT and generating an output signal to be transmitted by the proxy transponder to the radar DUT by swapping roles of a normal sideband component and a ghost sideband component of the output signal such that the ghost sideband component appears to the radar DUT as a desired emulant and the normal sideband component appears to the radar DUT an undesired ghost sideband component. The method further includes transmitting the output signal to the radar DUT.
