针对当前飞行目标红外辐射仿真计算存在的条件适用性较差的问题, 采用较为简便且可靠的建模方法, 对飞行目标红外辐射按辐射来源进行划分, 并建立各部分红外辐射模型。以该模型为基础, 在CVI环境中编写了针对不同条件下飞行目标红外辐射特性的仿真计算程序。通过计算实例, 对不同条件下目标飞行辐射特性进行分析, 得出其水平方向上最大及最小辐射强度。在与其他参考文献的数据进行对比后, 得出该仿真计算方法具有较高的可行性及准确性的结论, 为红外目标的硬件模拟提供了理论基础。

Considering that the simulating calculation of aircraft infrared characteristics has poor adaptability to the conditions,we used simple and reliable modeling method,classified the infrared radiation by the radiation sources,and established the infrared radiation model of each part.Based on the model,the simulating calculation program of aircraft infrared characteristics under different conditions was designed by using CVI.The aircraft infrared characteristics under different conditions were analyzed by using the calculating example,and the extreme values of radiation intensity were obtained.Compared with the data given in other references,our simulating method has higher feasibility and precision,which can provide a theoretical basis for infrared target simulation in hardware.
