摘要
A wind flow sensing system for determining wind flow at a set of different altitudes above a terrain is provided, The wind flow sensing system comprises an input interface configured to receive a set of measurements of radial velocities at line-of-site points above the terrain for each of the altitudes, and a processor configured to estimate velocity fields for each of the altitudes based on data assimilation of the velocity fields above an approximation of the shape of the terrain with a set of one or multiple convex shapes to fit the measurements of radial velocities and estimate horizontal velocities at each of the altitudes as a horizontal projection of the corresponding radial velocities corrected with corresponding horizontal derivatives of vertical velocities of the estimated velocity fields. The wind flow sensing system further comprises an output interface configured to render the estimated horizontal velocities at each of the altitudes.
