Claim 8:
9. A method for light detection and ranging (LIDAR), comprising:
generating a continuous wave (CW) optical beam and a frequency modulated CW (FMCW) optical beam;
sampling a CW local oscillator (LO) signal from the CW optical beam and an FMCW LO signal from the FMCW optical beam;
combining the CW optical beam and the FMCW optical beam into a combined optical beam;
transmitting the combined optical beam toward a target;
splitting 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;
detecting a first beat frequency from a combination of the CW return signal and the CW LO signal, the first beat frequency corresponding to a velocity of the target;
and
detecting a second beat frequency from a combination of the FMCW return signal and the CW return signal, the second beat frequency corresponding to a range of the target.
