| description | A Lidar system and method of detecting an object is disclosed. The Lidar system includes a photodetector, a spectrum analyzer and a processor. The photodetector generates an electrical signal in response to a reflected light beam received at the photodetector, the reflected light beam being a reflection of a chirp signal from the object. The electrical signal has a bandwidth the same as a bandwidth of the chirp signal. The spectrum analyzer includes a power divider that partitions the electrical signal into a plurality of channels, an analog-to-digital converter that converts the electrical signal within a selected channel from an analog signal to a digital signal, and a comb filter that provides output from the selected channel from the power divider to the analog-to-digital converter. The processor determines a parameter of the object from the digital signal in the selected channel. |
