空间目标可见光反射特性的研究

为提高空间对抗能力,提出了空间目标可见光反射特性控制的方法,在空间目标表面设计过程中尽量避免漫反射,采用镜面反射方式,同时目标本体采用多面体结构设计.以地基可见光探测为例,选择高度为250km圆轨道上的圆锥体目标和高度为900km圆轨道上的圆柱体目标为对象,分析了地基可见光遥感器对其探测能力与几何位置的关系.由空间目标可见光反射特性的研究得到结论,在多面体结构空间目标的表面设计中采用镜面表面设计,使可见光遥感器对它的探测能力明显降低,且由探测到的目标光谱特征无法判断目标的真实外形,从而达到控制空间目标可见光反射特性的目的.研究对未来空间目标的外形设计控制具有一定指导意义。

Visible light reflection characteristics of space target

For the purpose of improving space countermeasure capabilities, a method to control visible light reflection characteristics was given. Polyhedral structure and mirror surface were used during the surface design. Diffuse reflection surface and spherical structure should be avoided. Then taking the a cone target in 250 km high orbit and a cylinder target in 900 km high orbit as examples, the visible area on the ground was analyzed. It is found that the visible area of space target decreases significantly for the design of mirror surface and the observed shape changes, which results in the stealth of space target. The research can provide some reference for the exterior design of space target.
