Abstract
A system for computation of wind velocity including a laser adapted to transmit a beam to a target, a collecting lens for receiving a beam returning from the target, and receiver optics comprising a multi-element detector array at a focal plane of the collecting lens, wherein for each element of the multi-element detector array there is a specific optical path in the atmosphere leading from the laser to the target and back from the target to the element; and processor apparatus operative to measure signal fluctuations of an element of the multi-element detector array, and compute therefrom crosswind velocity of wind in the atmosphere, wherein said processor apparatus is operative to calculate turbulence strength changes and wind profiles.
