Abstract
A light detection and ranging system includes a transmitter transmitting a transmitted light pulse timing sequence, with pseudo-random timing and including a plurality of light pulses, toward a target. An optical receiver receives a reflected light pulse timing sequence including a plurality of light pulses from the target. An electronic control unit identifies a time delay between the transmitted light pulse timing sequence and the reflected light pulse timing sequence as a function of a correlation between the transmitted and reflected light pulse timing sequences.
