1. A coherent lidar system, comprising:

  • a first light source and a second light source configured to respectively output a first continuous wave and a second continuous wave;

    a first modulator and a second modulator configured 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;

    a beam combiner configured to combine the first FMCW signal and the second FMCW signal into a combined FMCW signal; and

    one or more aperture lenses configured 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.
