Infrared Propagation and Detection - FAS

Equation 1. Maximum IR detection range in vacuum. Note that the factor for atmospheric attenuation, t, has been omitted from this equation. Recall that the atmospheric attenuation is a function of range. This would make it impossible to write an equation for range in a closed-form. Therefore, the maximum range that is predicted by this formula ...
