Abstract
A LiDAR system and method includes a pulse modulation circuit and an amplitude modulation circuit for applying pulse modulation and amplitude modulation to a continuous signal to generate a plurality of amplitude-modulated pulses of the continuous signal. An optical modulation circuit applies the amplitude-modulated pulses of the continuous signal to an optical signal to generate a pulse amplitude-modulated (PAM) optical signal. Optical transmission elements transmit the PAM optical signal into a region, and optical receiving elements receive reflected optical signals from the region. Receive signal processing circuitry uses quadrature detection to process the reflected optical signals.
