1. A LIDAR system, comprising:
a first transform component configured to perform a complex mathematical transform on first signals; and
a second transform component configured to perform a real mathematical transform on second signals,
an output of the second transform component having multiple different peaks that each occurs at a frequency that is a candidate for a beat frequency of the second signals; and
electronics configured to use an output of the first transform component in combination with an output of the second transform component to generate LIDAR data,
wherein the electronics being configured to use the output of the first transform component in combination with the output of the second transform component includes the electronics being configured to use a peak in an 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.
