Abstract
A LIDAR system and method for determining a distance and a velocity of a target. The LIDAR system can include laser bank () is configured to generate a laser field from a first laser beam having a positive frequency sweep and a second laser beam having a negative frequency sweep, an optical combiner (), an optical coupler (), a photoreceiver (), and a control circuit (). The optical coupler direct a first portion of the laser field at the target such that the first portion is reflected by the target to the optical combiner. The optical combiner can optically combine the portions of the laser field. The output an 1-output () and a Q-output () according to the optically combined portions of the laser field. 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.
