Abstract
A coherent lidar system, a method of assembling the system and a vehicle including the system involve a light source to output a continuous wave, and a modulator to modulate a frequency of the continuous wave and provide a frequency modulated continuous wave (FMCW) signal. The system includes a a splitter to split the FMCW signal to two or more paths, and two or more aperture lenses. At least one of the two or more aperture lenses is associated with each of the two or more paths and is configured to obtain a receive beam resulting from a reflection of an output signal obtained from the FMCW signal.
