为研究双机空战中目标机采用低发射率红外材料后对攻击机机载红外搜索跟踪系统探测距离和概率的影响，建立了飞机运动过程和机载红外搜索跟踪系统探测距离计算模型，得到了相向飞行、同向飞行和侧向飞行三种典型的双机空战过程中探测距离和概率随飞行时间、速度、轨迹的变化规律。计算中考虑了目标的光谱辐射特征、大气透过率和探测器性能等因素对探测距离和概率的影响。结果表明目标机采用低发射率红外材料抑制红外特征后，在相同探测概率的情况下，探测距离明显减小；在攻击机与目标机相同距离的情况下，探测概率明显下降。

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.
