Abstract
A MIMO target emulation system for testing a mmWave radar sensor having multiple radar transmitters and receivers includes a coupling probe antenna array for receiving radar signals from the radar transmitters and for sending emulated target echo signals to the radar receivers; emulator receivers for down converting and digitizing the radar signals; a processing unit that decouples the digital radar signals, retrieves target parameters corresponding to emulated targets, generates emulated target echo signals corresponding to the targets in response to the decoupled digitized radar signals using the target parameters, and pre-decoupling the emulated target echo signals; and emulator transmitters for performing digital to analog conversion of the emulated target echo signals and up converting frequencies of the analog emulated target echo signals. The emulator transmitters simultaneously send the analog emulated echo target signals to the radar sensor via the antenna array to emulate target echoes responsive to the radar signals.
