Abstract
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 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.
Claims20
A method comprising:
- 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;
- and
- sending the one or more data measurements to a processor operative to perform data processing comprising:
- extracting one or more shock front distances from the one or more data measurements;
- calculating one or more shock front angles from the one or more shock front distances;
- and
- calculating one or more air data parameters from the one or more shock front angles.
A system comprising:
- a light detection and ranging (LiDAR) air data system, comprising:
- a LiDAR unit comprising:
- a laser configured to generate and emit a light beam transmitted to at least one interrogation region along at least one line of sight;
- and
- a light sensor coupled to the laser and configured to receive a backscattered portion of the light beam;
- and
- a processing system coupled to the LiDAR unit, wherein the processing system is operative to:
- receive one or more data measurements corresponding to the backscattered portion of the light beam;
- extract one or more shock front distances from the one or more data measurements;
- calculate one or more shock front angles from the one or more shock front distances;
- and
- calculate one or more air data parameters from the one or more shock front angles.
A non-transitory computer readable medium including instructions which, when executed by one or more processing devices, cause the one or more processing devices to:
- receive one or more data measurements from at least one light detection and ranging (LiDAR) unit;
- extract one or more shock front distances from the one or more data measurements;
- calculate one or more shock front angles from the one or more shock front distances;
- and
- calculate one or more air data parameters from the one or more shock front angles.
