The invention provides a multiple access method of an air vehicle cooperative information network, comprising a time-frequency space domain joint signal transmission system, a transmission target space domain determining method and a specific access procedure, wherein the time-frequency space domain joint signal transmission system determines a transmission frame structure applicable to a high-dynamic environment between nodes, and achieves the time-frequency space domain joint transmission of a transmission frame by means of discrete pulses. According to the transmission target space domain determining method, in a specific transmission process, a sending node is used for determining an antenna coverage area where a receiving node is located, thereby supporting the sending node to determine an antenna usage scheme when transmitting the specific information. The node access procedure is used for determining access procedures in specific node information transmission, network maintenance and other processes in
