Abstract
An optical air data system for an air vehicle includes a LIDAR module and a data processing module. The LIDAR module is configured to emit at least three laser beams, not all located in a common plane, and perform LIDAR measurements of a backscattered component of each of the laser beams. The data processing module includes a processor and machine-readable instructions that, when executed by the processor, processes the LIDAR measurements to determine at least one optically-based air data parameter. The overlap between the laser beams and one or more fields of view of the LIDAR module may be within two meters from the LIDAR module to determine the at least one optically-based air data parameter at short range from the air vehicle.
