摘要
鉴于设计Galileo导航卫星上激光后向反射器的需要,采用理论计算和实验验证的方法对角反射器的光行差补偿设计和远场衍射光强分布进行了研究。对不同直角偏差、是否镀反射膜的角反射器远场衍射光强分布给出了计算和试验结果。研究结果表明:理论计算与实验结果是完全一致的;对类似Galileo卫星的角反射器设计采用光行差角补偿是必要的,以及采用反射面不镀膜是合适的。
This paper mainly discusse the design theory and various experiments of retro-reflector on Galileo navigation satellite.It is given out the calculated and experimental results of far field diffracting distribution of the laser retro-reflector.The work has been done on different corner angle aberrance and on retro-reflectors with and without film.Our researches indicate that:it is necessary to take aberration compensation into account in the corner-cube reflector design of navigation satellites as Galileo,and it is appropriate to design the reflecting surfaces without coating.
