【摘要】 文中建立了高速飞机红外特性的物理模型 ,在考虑飞机内部传热、气动加热和太阳、天空、地面等背景辐射以及大气衰减的基础上计算得出了飞机 8～ 14 μm波段的辐射特性。分析对比了不同飞行速度、不同探测路径等条件下飞机的辐射特性 ,并进一步利用计算结果生成了模拟的红外图像。更多还原

【Abstract】 In the article,a physical model of IR signature from high-speed aircraft is constructed.The IR character of high-speed aircraft is elicited on the base of considering the diathermanous of aircraft,the pneumatic heat,the atmospheric attenuation and background radiation including the sun,the sky and the earth.The Model has the capability to analyzing the operation of aircraft in flight at various speeds,viewing angels,and spectral response of the seeker.Ulteriorly,using the result,the simulation of IR image is created.更多还原
