Classification: CPC G | IPC G

Claim 14:
15. A non-transitory computer readable storage medium having computer program code stored thereon, the computer program code, when executed by one or more processors implemented on a light detection and ranging system, causes the light detection and ranging system to perform a method comprising:
selecting a second signature for a second laser beam that is different than a first signature utilized in a previously transmitted laser beam, the second laser beam including one or more pulses;
encoding the second signature in the second laser beam;
transmitting the second laser beam via a first transmitter;
receiving, with a receiver, a third laser beam and generating a return signal corresponding to the third laser beam, wherein the third laser beam comprises (i) a portion of the second laser beam reflected by an object or (ii) a distinct laser beam transmitted by a second transmitter;
extracting a return signature from the return signal;
determining whether, within respective thresholds, the return signature matches the second signature based, at least in part, on one or more pulses of the return signature, wherein the respective thresholds are configured to be adjusted based on a variation of performance parameters; and
when the return signature is determined to match the second signature, determining a distance between the receiver and the object using at least one pulse of the one or more pulses of the return signature, such that the at least one pulse of the return signature is used to i) identify the return signature as matching the second signature and ii) determine the distance between the receiver and the object.
