Abstract
Disclosed is a multi-channel coherent LiDAR apparatus. The LiDAR apparatus includes a plurality of analog-to-digital converts (ADCs) each configured to receive reflected light reflected by a target and to convert the reflected light into a digital signal, one or more modulation units configured to receive the digital signals that have passed through some or all of the ADCs and channel signals having different frequencies or types and to modulate the digital signals, an adder configured to integrate the signals that have been modulated and received from the modulation units, a fast Fourier transform (FFT) unit configured to convert one signal integrated by the adder into a signal in a frequency domain, and a detection unit configured to detect the information on the distance of the target based on the signal converted into the signal in the frequency domain through the FFT unit.
