Abstract
The LIDAR system includes a first transform component configured to perform a complex mathematical transform on first signals. The LIDAR system also includes a second transform component configured to perform a real mathematical transform on second signals. Electronics are configured to use an output of the first transform component in combination with an output of the second transformation component to generate LIDAR data. The electronics are further configured to use a peak in the output of the first transform component to identify the peak in the output of the second transform component that is located at the beat frequency of the second signals.
