Using the One-Shot system, under development by the Defense Advanced Research Projects Agency (DARPA), a new electro-optical system will calculate the ballistics for him, telling him where to aim and ensuring a perfect shot -- no matter the weather conditions

How can a scope measure downrange cross winds?

Would you trust this for a hostage situation?

Some things are just better left in human control.

"Ultimately, One Shot programme chiefs expect that any sniper team equipped with their kit will be able to make one-shot kills six times out of 10 or better out to 1500m regardless of crosswinds etc, using any of the normal types of ammo currently used by US and British snipers: namely .300 Winchester magnum, .338 Lapua magnum and ordinary 7.62mm NATO."

1
Check your anemometer. Make sure your transmitting transducer and receiving transducer are both set.
2
Send a short burst of sound into the air with the transmitting transducer. Note the time between transmission and the reception of sound by the receiving transducer. This is called the time of flight, or TOF.
3
Calculate the perceived speed of sound by dividing the distance between the two transducers by the time of flight.
4
Rewrite this calculation as C(perceived) = C(wind) + C(air).

C(air) is the standard speed of sound.
5
Calculate the speed of wind by subtracting the standard speed of sound from the perceived speed of sound.

Several systems are currently under development by US-Israeli and DARPA initiatives. A joint US-Israeli development, under Israel's Defense Research & Development Directorate (DRDD) management currently under development at ITL, utilizes a cross-wind laser measurement concept, developed by Dr Joseph Shapira from Soreq Nuclear Research Center. This is evaluating fire control systems designed to improve the sniper team's performance. ITL unveiled a model of this system, dubbed 'Focus', designed as a fire control system to be operated by the sniper team spotter, supporting up to eight sniper positions simultaneously. The system employs a laser beam that instantly measures and profiles wind-flow, creating a three-dimensional model used in the ballistic calculation. Focus will provide each sniper with individual ballistic correction, based on accurate measurements of cross-wind downrange, temperature, range and inclination.

How many times is the wind stronger at the top of the bullets trajectory than at the line of sight? Laser beams fly straight, how can they measure for wind that will be above them? Or will the beam be broadcast in a vertical manner too?
