动态红外图像的计算机仿真技术研究

Study of the Computer Emulation for Dynamic Infrared Images

针对红外探测系统,进行了动态红外图像的计算机仿真生成技术研究.主要解决了以下四个问题:1.分析了飞机目标的红外辐射特性,包括发动机尾焰、尾喷口及飞机蒙皮的辐射计算方法;2.讨论了大气衰减对目标红外辐射特性的影响,对利用理论模型得到的目标红外辐射图像进行了修正,获得了较接近实际的模拟红外热图像;3.对探测成像系统的噪声仿真进行研究;4.完成软件编程,实现动态红外图像的仿真生成.

For the infrared detecton system, the emulation for dynamic infrared images is studied. The main works are as follows： 1. The infrared radiation characteristics of aircrafts are analyzed ,including the radiation characteristics of the engine,the tail flame,the final nozzle and the aircraft skin. 2. The effect of atmospheric transmission on the infrared radiation feature of the target is discussed. The target infrared radiation patterns obtained by theory models are improved with the atmospheric infrared radiation transmission and emission. The simulated thermal infrared radiation images that were corrected are more similar to the real ones. 3. The emulation for the noise of the imaging system is discussed. 4. By programming for the software ,the emulation for dynamic infrared images can be done.
