Abstract

Detection distance is an important index of infrared imaging system, and meteorological parameters are one of the main factors affecting the detection distance. The calculation model based on the detection distance of infrared detector point source is calculated by using MODTRAN software. Peel off the factors associated with the environment. Selecting typical weather conditions to calculate the detection distance of infrared detector's point source target. The detection distance under different atmospheric parameters is obtained, and the sensitivity analysis is carried out between the detection distance of infrared detector and the parameters of the meteorological environment. The results show that the detection distance is influenced by the parameters such as temperature, humidity, pressure, visibility, wind speed and so on, and is linearly related to these meteorological parameters.
