Abstract
A LIDAR system is configured to output a system output signal that travels away from the LIDAR system and can be reflected by objects located outside of the LIDAR system. The system output signal has a frequency versus time pattern with a repeated cycle. Each cycle of the frequency versus time pattern includes multiple data periods configured such that the system output signal is chirped differently in different data periods. The LIDAR system also includes electronics configured to generate multiple different sets of LIDAR data. Each set of LIDAR data indicates a radial velocity and/or separation between the LIDAR system and one or more of the objects located outside of the LIDAR system. Each set of LIDAR data is generated from light that is included in the system output signal during a group of multiple data periods. The groups of data periods including one or more common data periods that are each included in two or more different groups of data periods.
