| 摘 要： | 红外告警系统的图象模拟对于系统的设计具有指导性的作用。本文对图象模拟内容和要求进行了讨论，分析了目标、背景、干扰、传感器的模型，红外告警系统的目标——飞机和导弹可被视作点目标。背景主要由大气、云层、太阳散射，地物场景等构成；系统传感器对信号的影响可用传递函数计算后再经傅里叶反变换得到，系统噪声可用随机数结合方均根值表示。最后，简要讨论了软件的结构。

| Abstract: | Image simulation is of great significance for designing infrared warning systems.The content and the requirement of image simulation in an infrared warning system is discussed and the models for simulating targets,back-grounds and sensors are analysized in this paper.Images of targets such as air-crafts and missiles can be considered as point sources.Backgrounds are mainly constructed by atmosphere,clouds,solar scatterings,terrains and surface features. The effect of sensors on signal can be obtained by computing transfer functions and implementing inverse Fourier transform. The system noise can be character-ized by a random number and root mean square values. |
