Original Abstract Submitted

A light detection and ranging (LiDAR) device includes a laser light irradiator configured to irradiate a pulsed laser light towards an object, a laser light receiver configured to detect a pulsed laser reflected light signal based on receiving the pulsed laser light reflected from the object, a signal analyzer configured to determine whether the pulsed laser reflected light signal is a low signal to noise ratio (SNR) signal based on comparing a level of the pulsed laser reflected light signal with a reference signal level, and a processor configured to, in response to a determination that the pulsed laser reflected light signal is the low SNR signal, adjust a dynamic range of an analog-to-digital converter (ADC) to sample the pulsed laser reflected light signal.
