Research of Micro wave and Laser Fusion for Satellite Internet Channel Characterization
Single ground mobile communication and satellite communication method have met difficulties in meeting the demand for large-capacity and high-speed transmission of communication in the new era.The interconnection satellite network of space and earth through the deep integration of microwave com-munication and laser communication can improve the communication rate and capacity of inter-satellite link through laser communication technology,improve the available bandwidth of star-earth link through Q/V band microwave communication technology,and solve the problem of saturation of spectrum re-sources in Ka and Ku bands,which can improve the efficiency of the frequency spectrum.We investigate channel characteristics of microwave satellite-earth link and laser interplanetary link.Typical influence factors such as blocking effect,Doppler shift,free-space propagation loss and atmospheric loss are simu-lated in link modeling channel,which can provide important references for the design of satellite networks for microwave and laser fusion.
