摘　　要：文中仿真红外成像制导导弹跟踪飞机目标的全过程，用编程的方法生成目标的动态红外图像。首先分析了目标的红外特性，利用ＬＯＷＴＲＡＮ７软件求出目标在每一时刻每一位置各部位到达导引头的辐射亮度，然后把辐射亮度量化成灰度等级，形成一个灰度数据库。最后用ＯｐｅｎＧＬ产生动画，动画过程中，目标各部分的灰度由计算机从灰度数据库中实时读取，然后再实时赋给对应红外图像上的像素，赋给各个部位的材质是自发光材质。A simulation of tracking a plane with an imaging infrared guidance missile is described in the paper. At first, the infrared characters of the plane are analyzed and the temperature of each part of the plane is got. The radiances of each part of the plane of each frame are computed with the software LOWTRAN7 and are turned into gray scale. Thus, a database of gray scale is formed. At last, the dynamic images are produced by programming with OpenGL. During the course of the animation, the computer reads the gray scale of each part of the target from the database and puts it on the corresponding pixels of the image in real time. The material of the plane is emitted material.
