摘　　要：通过建立微光夜视仪最大作用距离S的计算模型,以及大气衰减系数K的数据拟合,提出了计算S的实用公式。利用计算或实验室测量的夜视仪分辨率α,即可模拟出用于描述微光夜视仪在不同大气环境下的最大作用距离的三维图形。By building a calculation model for the maximal operating distance of low-light level night vision instruments, and data fitting of atmospheric attenuation coefficient, a practical equation for calculating the maximal operating distance is presented. By using the definition solution of low-light level night vision instruments which was measured in the lab or calculated, the maximal operating distance in different atmospheric environments can be simulated with a three dimensional description.
