Abstract
A wind flow sensing system determines a first approximation of the velocity field at each of the altitudes by simulating computational fluid dynamics ( CFD ) of the wind flow with operating parameters reducing a cost function of a weighted combination of errors , determines a horizontal derivative of vertical velocity at each of the altitudes from the first approximation of the velocity fields , and determines a second approximation of the velocity fields using geometric relationships between a velocity field for each of the altitudes , projections of the measurements of radial velocities on the three - dimensional axes , and the horizontal derivative of vertical velocity for the corresponding velocity field . In the cost function of the CFD , each error corresponds to one of the altitudes and includes a difference between measured velocities at the line - of - site points at the corresponding altitude and simulated velocities at the line - of - site points simulated by the CFD for the corresponding altitude . At least some errors in the weighted combination have different weights .
