Abstract
For correctly estimating the detection distance of the infrared system to the ground target, this paper establishes a physical model of a typical ground target and numerically calculates the temperature distribution of the target surface, then analyzes and calculates the infrared radiation intensity distribution of the ground target in the 3~5μm. Secondly, the radiation attenuation in the atmosphere are considered, then a operating range equation of IR detection system to a target is given, and a step-by-step approximation method is presented for obtaining the feasible solution to the equation. Finally, for a case, operating ranges are gained at various weather environment and detecting angle. Some meaningful conclusions have been drawn, providing an important theoretical basis and technical support for infrared stealth and protection of ground targets.
