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.
