用于深空探测的彗星光学信号模拟方法

Simulation method of optical signature of comet for deep space exploration

研究了彗星的光学信号模型,依据彗星的光学信号模型,分别采用粒子系统和反射度纹理与光照叠加的方法对点信号和面信号进行模拟,实验证明该模拟方法简单有效,可为深空探测尤其是彗星撞击探测中光学导航相机地面测试实验提供可靠的光学输入信号。

Optical signature model of the comet was researched.By the optical signature model of the comet,the particle system was used for the simulation of the optical signature of the comet when it looked like a point and the method of reflectional texture adding the illuminations was used for the simulation of the optical signature of the comet when it looked like a surface.The experiments show that this simulation method is simple and efficient,and can provide reliable optical input signals for deep space explorations especially for the ground experiments of optical navigation cameras among the comet impact.
