Abstract: A coherent lidar system includes a first light source and a second light source to respectively output a first continuous wave and a second continuous wave, and a first modulator and a second modulator to respectively modulate a frequency of the first continuous wave and the second continuous wave to respectively provide a first frequency modulated continuous wave (FMCW) signal and a second FMCW signal. The system also includes a beam combiner to combine the first FMCW signal and the second FMCW signal into a combined FMCW signal, and one or more aperture lenses to transmit an output signal obtained from the combined FMCW signal and to obtain a return signal resulting from a reflection of the output signal by a target.
