ABSTRACT:
The invention is a line of sight wind detection system that has a laser with an output that is directed at a target. The system also has a receiver with a Hartmann aperture array receiving a reflected beam impinging on the Hartmann aperture array. A multiple pixel sensor senses a number of spots of light from the Hartmann aperture array. An analyzer receives an output from the multiple pixel sensor and determines an effective wind speed along a line of sight using a position of the spots. The system takes advantage of the fact that the wind along the line of sight will result in a shift in the angle of the wave front of the reflected beam. This shift in the angle of the wave front contains all the information of the cumulative effect on a projectile fired at the target.
