中文摘要：

针对新型红外成像系统的成像特性,通过对光电场景图像与系统输出图像特性的客观比较,推导了场景图像灰度到光电成像系统输出图像的灰度转换模型;首次提出了基于系统级的测量参数：SiTF、MTF、NETD、噪声等效背景照度的光电输出成像的仿真方法,并给出了仿真结果.最后现场试验验证了其合理性.

英文摘要：

In this paper, focusing on the electro -optical imaging character, according to the objective compare of characteristic for scene to imaging system output image, the gray conversion model of scene to imaging system output image is first derived, an imaging simulation approach based on system level measurement parameters： signal transfer function, modulation transfer function, noise equivalent differential temperature, and noise equivalent background radiant is proposed , and simulation results are given. In the end, scene experimentation is validated.
