文中提出了红外成像引信的计算机仿真方案 :首先是建立飞机的红外辐射模型 ,建立不同部位 (单层蒙皮、内有热源蒙皮、油箱 )的热平衡方程 ,进而得到相应波长范围内的红外辐射强度 ;接着提出了弹目交会的数学模型 ,以获得各种交会状态下的飞机红外图像 ;然后提取包括边角位置、方位和角度大小的图像特征 ;最后用神经网络的方法对所得特征集进行模式分类。 In this paper, a computer simulation scheme of infrared imaging fuze is proposed. The first is to establish the infrared radiation model of the aircraft and establish the heat balance equation of different parts (single skin, heat source skin and fuel tank) to obtain the infrared radiation in the corresponding wavelength range Then, the mathematic model of the projectile intersection was proposed to obtain the aircraft infrared images under various rendezvous states. Then the image features including the position, azimuth and angle of the corner were extracted. Finally, the neural network was used to conduct the feature set Pattern classification.
