Networking topologic structure of fleet formation and design method for combined multi-address system

Abstract

The invention relates to a networking topologic structure of fleet formation and a design method for a combined multi-address system, belonging to the technical field of the aviation data link, radio navigation and aircraft automation. The invention provides a multi-address system and a networking topologic structure for networking communication and measurement of fleet formation, meets the passive detection and location and the cooperative attack task of the fleet formation to the moving-target. The invention provides the networking topologic structure which can realize the combined multi-address system and support the fleet formation on a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array) apparatus and a radio frequency channel on an intermediate-frequency signal processing circuit board of a fleet link terminal. The invention provides two novel multi-address access systems of communication topologic configuration, namely the CDMA Code Division Multiple Access) / FDAM combined multi-address communication system of the fleet formation based on cross-link networking topology and a graded hierarchical multi-address communication system of the fleet formation based on tree topology. The former can support a single-hop access mode of total network coverage and the latter provides a multiple-hop access mode of total network coverage.

Description

technical field [0001] The invention relates to a network topology structure and a combined multiple address system design method for fleet formation, and belongs to the technical fields of aviation data link, radio navigation and aircraft. Background technique [0002] At present, domestic and foreign machine group networks are based on data link systems, such as Link-11, Link-16, JTIDS, and so on. The multiple access methods of these data link systems are based on time-division multiplex communication, and do not support ranging, speed measurement, and time synchronization between aircraft. In addition, the cluster formation network topology under the traditional data link system is relatively simple, and the topology of the multi-access communication network is only formed according to the needs of information interaction, and the space cooperative network topology suitable for specific tasks has not been formed. Contents of the invention [0003] The purpose of the pr...
