摘　　要：通过分析反舰导弹的红外辐射特征,给出了不同气象条件和传输路径上红外大气传输的衰减方程,然后给出舰载红外系统对反舰导弹红外探测能力的计算模型。在模型的求导过程中,考虑了光机扫描型和凝视型两种红外系统的不同,结合影响探测能力的多种因素,进一步完善了光机扫描型和凝视型红外系统的作用距离方程和目标发现概率计算模型,可对不同气象条件下舰载红外系统在不同方位上的探测能力进行理论分析和系统的综合性能评价。By analyzing the infrared radiation characteristics of anti-ship missiles,the attenuation function of infrared atmospheric transmission in different weather condition and route is given,then a detectability calculation model of shipborne IRST system on anti-ship missile is established.The influence factors of detectability and the difference between scanning IRST system and staring IRST system is considered,and the operation range function and detection probability model of scanning IRST system and staring IRST system are improved,which can be used to theoretically analyze the detectability of and capability estimation of IRST system in different weather condition and target direction.
