摘要
为了实现对红外成像系统静态性能计算机仿真评估,提出一种用于静态红外成像系统图像的生成方法。红外成像系统的调制传递函数(MTF)和噪声是系统图像的主要影响源,针对这一点,对系统调制传递函数和各类噪声源分别进行分析和建模,再根据红外目标和背景的辐射特性建立红外标准图像。通过模型的建立最终得到红外仿真图像,结果表明该方法具有很好的应用前景。
A method of infrared (IR) imaging simulation is put forward in order to test and evaluate the IR imaging system. Modulation transfer function (MTF) and noise greatly influence the image of IR imaging system. According to this, MTF and every components of noise are analyzed and models are also set up. Then IR standard image is set up by the characteristic of radiance. By the works above, simulation images are got, and the results show that the new algorithm has great prospects.
