Abstract
The passive technique for crosswind velocity retrieval from a video series of incoherent images, developed in previous works, has been tested. The technique is based on the visualization of air-drifted turbulent air inhomogeneities which distort optical images recorded. The results of retrieval of the crosswind velocity by the technique suggested are compared with anemometer measurements at paths of up to 1 km in length.
