Methods, systems, and computer readable media for phase-conjugate radar target emulation for testing dual sideband (DSB) frequency modulated continuous wave (FMCW) radars

A system for phase-conjugate target emulation for testing a dual sideband (DSB) frequency modulated continuous wave (FMCW) radar, the system comprising:

• a radar scene emulator including at least one processor, a memory, and an array of frequency-shifting transponders for emulating physical radar targets;
• a transponder selector implemented by the at least one processor for selecting, as a proxy transponder to transmit an emulated target radar signal to a radar DUT, one of the frequency-shifting transponders from the array of frequency-shifting transponders at a mirror image location with respect to a desired direction of arrival of a signal from an emulated radar target;
• wherein the proxy transponder is configured to:
• receive a radar signal from the radar DUT;
• generate an output signal to be transmitted 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 as an undesired ghost sideband component;
• and
• transmit the output signal to the radar DUT.
