Abstract
A LIDAR system and method for determining a distance and a velocity of a target. The LIDAR system can include a laser modulated by a laser modulator, an optical combiner, an optical splitter, a photoreceiver, and a control circuit. The optical splitter can optically split the modulated laser beam into a first laser beam and a second laser beam and direct the first laser beam at the target such that the first laser beam is reflected by the target to the optical combiner. The optical combiner can optically combine the first laser beam and the second laser beam. The output an I-output and a Q-output according to the optically combined first laser beam and second laser beam. The control circuit can determine a nominal beat frequency, which corresponds to the distance of the target, and a frequency shift, which corresponds to the velocity of the target, accordingly.
