Frequency modulated continuous wave (FMCW) radar target emulation with synchronized modulation reflection devices

A system for testing a vehicular radar, comprising:

• a controller comprising a memory that stores instructions, and a processor that executes the instructions, wherein the instructions, when executed by the processor, cause the processor to execute a three-dimensional (3D) scenario simulation configured to generate drive scenarios including targets in a surrounding environment of the vehicular radar;
• and
• a target emulator configured to transmit an emulated radar reflection signal to the vehicular radar corresponding to the drive scenarios generated by the 3D scenario simulation,
• wherein the target emulator comprises a radar detector configured to detect a radar signal frame emitted by the vehicular radar, and an emulation transmitter configured to generate the emulated radar reflection signal of a target being emulated;
• wherein the instructions further cause the processor to:
• generate control signals which control the emulation transmitter according to at least one characteristic of the target being emulated;
• determine a current radar parameter among plural possible radar parameters of the radar signal frame of the vehicular radar;
• adapt the control signals which control the emulation transmitter according to the determined current radar parameter of the radar signal frame of the vehicular radar.

A tangible, non-transitory computer readable medium that stores instructions, which when executed by a signal processor of a system for testing a vehicular radar cause the processor to:

• receive a signal corresponding to a radar signal frame emitted by the vehicular radar;
• drive an emulation transmitter to generate an emulated radar reflection signal of a target being emulated;
• control the emulation transmitter according to at least one characteristic of the target being emulated;
• determine a current radar parameter among plural possible radar parameters of the radar signal frame of the vehicular radar;
• and adapt control signals which control the emulation transmitter according to the determined current radar parameter of the radar signal frame of the vehicular radar, wherein the plural possible radar parameters include at least one of an instantaneous frequency and an instantaneous power.
