In order to study of the influence of low emissivity infrared materials on the range and probability of detection of infrared search and track system for attack aircraft in air combat, aircraft flight process and infrared search and track system detection process model were established, the trend of the range and probability of detection with time, velocity and locus in three typical air combat process such as opposite, same and side direction were obtained. In the calculation, the influence for target spectral radiation characteristics, atmospheric transmittance, detector performance and other factors on the range and probability of detection were considered. The results show that after infrared suppression measure are taken by target aircraft, the range of detection is decreased significantly in the case of the same probability of detection, the probability of detection is decreased significantly in the case of the same distance of attack and target aircraft.
