深空动态场景目标红外图像仿真研究

针对深空背景空间目标的红外图像仿真问题,首先根据热平衡理论,对典型空间目标进行建模,得到目标不同部分的温度;然后建立目标的红外辐射模型,得到目标的红外辐射光谱特性;接着提出了一种基于红外星表数据库的星空背景建模方法,模拟任意时刻,任意视场大小和指向的红外星空背景;最后得到了不同距离、不同姿态空间目标与深空背景合成的红外图像仿真序列,实现了探测器不断接近目标过程中的红外辐射图像仿真.

Dynamic Target IR Image Simulation in Deep Space Background

For the problem of simulating space target IR image in deep space background, a modelling was presented, and the temperatures of different parts based on the theory of thermal equilibrium were gained. The IR spectrum of target were simulated by the IR mathematic model. Followed, based on the IR catalogue data, an approach for modelling the celestial background observed in any time, on any eyeshot and at any visual angel, is presented. Finally, by obtaining the infrared images background at any distance and on any target pose, the course approaches target have been simulated. sequence composed by the target and of IR images that detector unceasing
