Abstract
Systems and methods are provided for determining the cross-stream component of wind velocity near a target location. A modal-decomposition of a first series of images is conducted to obtain a plurality of contribution functions representing the first set of images. A second series of images is mapped to a selected subset of the plurality of contribution functions to create a set of reconstructed images. At least one characteristic of the set of reconstructed images is measured to estimate the cross-stream component of the wind velocity near the target location.

A method for determining a cross-stream component of wind velocity near a target location, comprising:
- conducting a modal-decomposition of a first series of images to obtain a plurality of contribution functions representing the first series of images;
- mapping a second series of images onto a selected subset of the plurality of contribution functions to create a set of reconstructed images;
- and
- measuring at least one characteristic of the set of reconstructed images to estimate the cross-stream component of the wind velocity near the target location.
A system for monitoring a cross-stream component of wind velocity near a target location, comprising:
- a sensor that captures a first series of images and a second series of images of the target location;
- a modal-decomposition component that generates a set of contribution functions representing at least a portion of wind energy represented by distortion within the first series of images;
- and
- a mapping component that maps the second series of images to the set of contribution functions to create a series of reconstructed images that facilitate the estimation of the cross-stream component of the wind.
A system for monitoring a cross-stream component of wind velocity near a target location, comprising:
- a sensor that captures a first series of images of the target location;
- a mapping component that maps the first series of images onto a set of contribution functions to create a series of reconstructed images containing at least one tracer feature that illustrates the cross-stream component of the wind velocity;
- and
- a parameter-measurement component that determines the cross-stream component of the wind velocity from the at least one tracer feature.
