Claim 0:
1. A light detection and ranging (LIDAR) system, comprising:
optical sources to emit a continuous-wave (CW) optical beam and a frequency-modulated CW (FMCW) optical beam;
a first optical coupler to generate a CW local oscillator (LO) from the CW optical beam;
a second optical coupler to generate an FMCW LO signal from the FMCW optical beam;
a first optical component to combine the CW optical beam and the FMCW optical beam into a combined 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 of the CW return signal and the FMCW return signal;
a first optical detector to detect a first beat frequency from a combination of the CW LO signal and the CW return signal, wherein the first beat frequency is associated with a velocity of the target; and
a second optical detector to detect a second beat frequency from a combination of the FMCW LO and the FMCW return signal, wherein the second beat frequency is associated with a range of the target.
