摘　　要：红外大气透过率是分析目标红外辐射特性和红外辐射反演计算的重要基础。针对Modtran等大气透过率计算软件难以与红外辐射特性测量系统集成的问题,在大气透过率经验公式基础上进行推导,提出一种适用远距离、任意传输路径的红外大气透过率的工程计算方法。方法基于传输路径上的地理位置对大气分层,使用实测数据提取大气模型参数,实现中等分辨率远距离中波红外大气透过率的快速工程计算。计算结果表明,工程计算得到的平均透过率接近Modtran,且易于与实时系统集成。The infrared atmospheric transmittance is the basis for analyzing the radiating characteristics of infrared target and infrared radiation introspection calculation.But the atmospheric transmittance calculation software as Modtran is hard to be integrated with infrared radiation characteristics measurement system.Based on the empircal formula,a engineering calculation method of infrared atmospheric transmittance suitable for long distance and arbitrary transmission path is presented.The method stratifies the atmosphere based on geographical location,obtains atmospheric model parameters with measured data,achieves a fast-engineering calculation of moderate resolution atmospheric transmittance in the long-range mid-wave infrared.The calculation results show that the average transmittance gotten by this method is close to Modtran and easy to integrate with the real-time system.
