Abstract
A light detection and ranging (LIDAR) system includes optical sources to emit a continuous-wave (CW) optical beam and a frequency-modulated CW (FMCW) optical beam, a first and second optical coupler to generate a CW local oscillator (LO), and an FMCW LO signal. The system further includes a first optical component to combine the CW optical beam and the FMCW optical beam, a second optical component to transmit the combined optical beam toward a target, a third optical component to split a target return signal into a CW return signal and a FMCW return signal based on polarization or frequency, a first optical detector to detect a first beat frequency from a combination of the CW LO signal and the CW return signal, and a second optical detector to detect a second beat frequency from a combination of the FMCW LO and the FMCW return signal.
