Claim 14:
15. A light detection and ranging (LiDAR) system, comprising:
a first optical source to transmit a portion of a first light signal towards a target;
a second optical source to transmit a portion of a second light signal towards a target;
an optical receiver to receive a first return signal from the target based on the first light signal and a second return signal from the target based on the second light signal,
a circuitry; and
a memory to store instructions that, when executed by the circuitry, cause the system to:
sample a first signal at the LiDAR system to produce a first set of samples around a first detected frequency peak related to the first signal;
sample a second signal at the LiDAR system to produce a second set of samples around a second detected frequency peak related to the second signal;
convolve a first function created based on the first set of samples and a second function created based on the second set of samples to produce a third function;
refine at least one of the first signal or the second signal to produce at least one of a first refined signal or a second refined signal based on the third function; and
extract range and velocity information related to a target based on at least one of the first refined return signal or the second refined return signal.
