    摘要
  • 摘要: 针对大气透过率是影响红外系统作用距离的重要因素，且随大气环境、波长、距离等因素而复杂变化难以精确描述，研究了大气透过率对红外系统作用距离的影响，提出一种基于离散光谱透过率的红外系统作用距离模型。使用MODTRAN 软件计算出波数间隔为1 cm-1的离散光谱大气透过率，建立大气透过率数据库，计算出波数间隔为1 cm-1的光谱区域内目标的红外辐射功率。应用该模型对实际的战斧巡航导弹进行计算，结果表明该模型具有更高的计算精确度与可行性。
    Abstract: Atmosphere transmittance, which is an important factor influencing the operating range of infrared system and couldn-t be described precisely because of its complex changing with the atmospheric environment, wavelength and range etc, becomes one of difficulties for calculating the operating range. The impact of atmospheric transmittance on the effect distance of the infrared system was studied. An infrared detection range model based on discrete spectral transmittance was proposed. The atmospheric transmittance of the 1 cm-1 wave number segments was calculated by the MODTRAN software and was used to calculate transmitting infrared radiation power in the 1 cm-1 wave number segments. The calculated data was used to calculate the operating range of the infrared image system, instead of using a constant or average atmospheric transmittance in traditional method. The presented model is applied to the calculation of Tomahawk cruise missiles. Results indicate that it has a high accuracy and feasibility.
