【Abstract】 Objective: In order to break through the laser communication technology of one point to multipoint, which is the difficult technology problems for laser communication with point to point. Methods: The networking soluions of the antenna structure with three concentric spheres are proposed. This antenna structure of three concentric spheres with the advantages of simple structure, small size and light weight, can be applied to short-distance space laser communication. The feasibility of the system can be realized from the two aspects of the analysis of link and the analysis of the precision index. On this basis, the whole optical system can be determined by the corresponding optical system design. Results: Under the condition of permitting of link energy, the optical system of antenna structure of three concentric spheres with mobile field azimuth angle of 120°and the pitching angle of 20°is completed. The parameters can meet the requirements in the subsystem of the communication receiving optical path, the communication transmitting optical path and the communication tracking optical system. Conclusion: The results indicates that the antenna structure of three concentric spheres can be applied to the laser communication networking. under the short-distance space.更多还原
