| description | An air data method and system are disclosed. In one implementation, the method comprises obtaining one or more data measurements from an interrogation region with at least one light detection and ranging (LiDAR) unit along at least one line of sight. The data indicate the distance of a shock front of a supersonic aircraft from the LIDAR sensor, along its line of sight. The method further comprises sending the one or more data measurements to a processor operative to perform data processing. The data processing includes extracting one or more shock front distances from the one or more data measurements, and calculating one or more shock front angles from the one or more shock front distances. The data processing further includes calculating one or more air data parameters from the one or more shock front angles; these air data parameters may comprise the Mach angle, the angle of attack or the angle of sideslip. |
