Estimation of Atmospheric Turbulence Parameters using Differential Motion of Extended Features in Time-lapse Imagery
A system and method provide improved remote turbulence measurement. The system includes an image capturing device that captures time-lapse images of a distant target anywhere from a km to more than a 100 km away. A processor of the system tracks relative motion due to atmospheric turbulence of some number of patches of definite size on each of these images using a subpixel accurate correlation technique. The processor computes differential tilt variances between every pair of patches from the image collection and evaluates the theoretical weighting functions between turbulence along the path and differential tilt variances. The processor determines weights to linearly combine the weighting functions such that the combined weighting function closely resembles the weighting function corresponding to a turbulence parameter of interest. The processor then combines the differential tilt variances using the determined weights to obtain the desired turbulence parameter.
