Description
technical field [0001] The invention belongs to the technical field of optical communication, and relates to a space-borne microwave photoelectric hybrid communication and exchange integration system and method. Background technique [0002] The spatial information network has the following characteristics: 1. The link is heterogeneous. Various satellite communication systems based on microwave links basically meet the needs of existing communication, navigation, remote sensing, and measurement and control tasks. Limitations make it difficult to meet the needs of various business transmission and distribution of the space-ground integrated network. The space optical communication system based on the laser link has the advantages of large capacity, small size, strong anti-interference ability, and good confidentiality. 2. The object of heterogeneous information interaction is single. The spatial information network is characterized by many types of services, many types of ...
