A simple method is described for transforming field visual target acquisition data (the standard data) to apply to different meteorological conditions, imaging system parameters, and visual acquisition levels (e.g., detection and recognition). For each probability of target acquisition in the standard data, a new value of range is computed which is appropriate to the new conditions. As an example, the method is applied to the case of optical sights for different values of magnification and for different meteorological visibilities and ambient luminances.
