摘要
依据红外辐射的基本原理,针对隐身飞机的发动机尾焰、尾喷口和飞机蒙皮三大主要辐射源,建立了隐身飞机的红外辐射模型,提出了基于温度场分布的飞机红外辐射计算方法,并对某型飞机的红外隐身效果进行了仿真。根据红外探测器的工作原理,得到经大气传输和目标与背景对比后探测器接收到的有效目标信息,仿真计算了探测距离随波长的变化情况。研究结果对隐身飞机的设计以及红外制导防空导弹武器系统的设计和应用提供了重要的参考依据。
According to IR radiation’s basic principle,aiming at IR radiation of stealth aeroplane from three major radiation sources including exhaust gases,the nozzle of the turbo jet engine and the skin of the aeroplane,a theoretical model is built to calculate the radiant intensity of stealth aeroplane and a calculating method of aeroplane’s IR radiation on the basis of temperature field distributing is advanced. A typical aeroplane is simulated and analysed. Based on IR detector’s work mode,the effective object information which the detector received after atmosphere’s transmission and contrast against background is gained,and spectral variation of detected distance was simulated. These conclusions provide a basis for stealth aeroplane design and the IR guidance air-defence weapon system design and application.
