I shoot service rifle at 600 yards on a range with wind flags at 100 yard intervals. It's not uncommon at that range for the wind to be blowing in opposite directions at each interval. At that range you can make an accurate read on the wind speed at the target purely from the mirage, reading vegetation movement is not necessary.
My understanding is that down range wind sensing systems do so by reading the mirage as well.
- thalur 14y agoI don't know if it is the same thing that you are alluding to, but LIDAR can be used to measure distant wind speeds. I don't know if the output would be suitable for shooting, but it has been used in sailing. https://en.wikipedia.org/wiki/LIDAR#Meteorology_and_atmospheric_environment https://en.wikipedia.org/wiki/LIDAR#Meteorology_and_atmosphe... http://optics.org/article/34878 http://optics.org/article/34878 http://www.gizmag.com/catch-the-wind-racers-edge-laser-wind-mapping/14083/ http://www.gizmag.com/catch-the-wind-racers-edge-laser-wind-...
- shpxnvz 14y agoThat's cool stuff. Seems like it could be useful if it could be miniaturized. ETA: The binocluar device in the last link is pretty close, if they can extend the range from 300m and drop the price tag from $150K!
