Abstract: A fire control system that includes an array of photodiode elements. For each element of the photodiode array, there is a specific optical path in the atmosphere leading from the laser to a target and back from the target to the element. Accordingly, each element of the detector array can be regarded as if illuminated by a distinct light source.

By measuring the signal fluctuations by any element of the photodiode array, it is possible to compute the crosswind velocity. By comparing signal fluctuations patterns of two or more elements it is possible to define the wind direction and to determine the turbulence strength value.
