摘　　要：针对在给定飞行状态下不能实时计算飞行器红外辐射的问题,提出了基于红外辐射理论、空气动力学及发动机的工作原理建立飞行器红外辐射强度的理论计算模型,主要包括蒙皮辐射及其反射和排气系统辐射两大部分。该模型在已知飞行高度、速度及加力情况下,对飞行器在不同观测角度和不同探测波段的红外辐射量进行了仿真计算。仿真结果表明,该模型可实时计算出飞行器在给定飞行状态下的辐射量,并通过Visual C++控制黑体温度,使其产生与实际飞行情况等量的红外辐射,实现了实验室环境下飞行器不同飞行状态的黑体模拟。Aiming at the problem that the infrared radiation of the aircraft can’t be calculated in real time under given flight conditions, the theoretical calculation model of infrared radiation intensity of the aircraft was estab-lished based on the infrared radiation theory^aerodynamics and working principle of engine, mainly including the skin radiation, its reflection and exhaust system radiation When the flight altitude, speed and after burning condition are known, the infrared radiation of the aircraft at different observation angle and during different de-tection waveband was simulated. The result showed the infrared radiation of the aircraft under given flight con-ditions could be calculated through this model in real time, and the temperature of the black body was controlled by Visual C＋ ＋ , the infrared radiation which was equivalent to the actual flight situation, the black body simu-lation of the aircraft under different flight conditions was realized in laboratory.
