A system for emulating an over-the-air environment for testing a Frequency-modulated Continuous Wave (FMCW) light detection and ranging (LiDAR) unit under test (UUT). The system includes an optical lens system that receives an FMCW laser signal from the LiDAR UUT, and provides the signals to one or more optical fibers. A slope, chirp timing and intensity of the FMCW laser signal is determined using digital signal processing, and a modulation waveform is determined to emulate an over-the-air (OTA) environment based at least in part on the slope, chirp timing, and intensity. An in-phase quadrature phase (IQ) modulator modulates the FMCW laser signal using the modulation waveform and provides the modulated laser signal back through the optical lens system to the LiDAR UUT.
