Thermal imaging devices are increasingly being used extensively in the military for surveillance and observation. There are many methods to calculate and evaluate the observation distance of thermal imaging devices, both theoretical and practical, with a range of different advantages and disadvantages. In this paper, the method of calculating the operating distance of thermal imaging device: Detection distance, identification and discrimination based on the minimum resolvable temperature difference (MRTD) measured in the laboratory according to STANAG- 4347 standard of NATO is presented. The method is applied to calculate the observation distance for the thermal imaging channel of a mixed day and night gunner viewfinder for a T-54B (T55) tanks.
