摘要
红外成像仿真是现代高科技的关键技术之一,在红外制导与对抗、反恐怖活动、遥感探测、交通安全等众多领域有着广泛的应用。各种复杂因素的影响导致地表温度的计算非常复杂。分析了影响地表温度边界条件的各种因素,通过建立地表瞬态热平衡方程,设定初边值条件,计算了地表温度随时间的变化关系,并与实际测量值进行了比较分析,结果表明理论计算较为准确。最后给出了仿真红外图像的方法。
Infrared （IR） Image Simulation is a key technique in current high science and technology, and has been found wide applications in many domains such as infrared guidance ＆ countermeasure, anti-terrorism, remote sensor detection, traffic safety, etc. It is very complicated to calculate the surface temperature of ground surface due to several factors. These factors influence boundary conditions of the ground surface temperature. The relation between temperature and time of ground surface is calculated by establishing the equations of the momentary thermal equilibrium and enacting initial-boundary value condition. The calculation method is proven to be correct according to the comparison between the calculated values and the measured values. The method of IR image simulating is presented.
