摘要
红外半实物仿真目标特性与实际的接近程度直接影响试验的结果,目标辐射特性的变化不仅与距离有关系,更受到大气环境的影响。本文基于以MOS电阻阵为核心的红外动态场景生成器的工作过程,对大气衰减的计算进行工程化的探讨,研究了大气吸收与大气散射对目标特性变化的影响,在探讨大气吸收的影响时着重与水蒸气和二氧化碳的影响,通过查表法来进行计算。在目标模拟中加入大气衰减环节,使目标特性的模拟更贴近于实际。
The comparability between the virtual target in the loop simulation system of infrared could influence the result. The change of the target＇ s infrared radiation not only had relationship with distance, it＇ s affected by the atmospheric condition more. This paper discussed the engineering calculation of the atmosphere attenuation and the influence of atmospheric absorbency to the change of the target＇ s infrared radiation according to the work of the MOS-Resistor-Array, also calculated the atmospheric transmittance according to lookup the tabulation especially the vapor and the carbon dioxide. It could make the virtual target close to the reality, when adding the atmospheric attenuation to the simulation of the target.
