红外成像引信的计算机仿真

文中提出了红外成像引信的计算机仿真方案：首先是建立飞机垢红外辐射模型，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；然后提取包括边解位置、方位和角度大小的图像特特；最后用神经网络的方法对所得特征集进行模式分类。

Computer simulation of imaging infrared fuse

Thesimulation scheme of imaging IR fuse is proposed. At first, the infrared model of airplanewas presented, the thermal equations of the different part of airplane (the skin withoutheat source, the skin with heat source and the skin of gasoline tank) were established,thus the infrared radiance within corresponding wave range was obtained. Secondly, themodel of target-mssile intersection was presented, and the infrared image of airplane invarious target-missile intersection was obtained. To the third, the corner featurecontaining position, angle, and orientation was extracted. Finally, images can beclassified by extracted feature sets using neural network.
