Wireless Ultraviolet(UV)communication can transmit information through the scattering of ultraviolet by gas molecules and atmospheric particles,and has the advantages of non-line-of-sight communication,strong anti-interference ability,low background noise,good confidentiality and all-weather working.This makes it have a good application prospect in the military field and complex environment.However,the current launch of UV LED devices with low power,coupled with the atmospheric absorption and scattering of complex particles,which makes the UV transmission distance shorter.UV mobile ad-hoc network is considered to be a free and flexible application of technology to effectively expand the scope of UV communication solutions.Therefore,it is of great significance to study the related technology of UV mobile self-organizing network,especially the research on node structure and inter-node communication performance of mobile ad hoc network.Aiming at the design and research on UV mobile ad hoc network communication system,the following several works are carried out:1.According to the atmospheric absorption and scattering properties of UV photons,the line-of-sight communication and non-line-of-sight communication link models and the coplanar and non-coplanar communication link models between UV communication nodes are analyzed.2.Based on the principle of space division multiplexing,a kind of ultraviolet mobile ad hoc network communication node device is designed,and the method of acquisition,pointing and tracking(APT)between communication nodes is given.The master-slave node acquisition time and the communication performance between nodes are simulated and analyzed,and the corresponding experimental platform of the UV communication system is set up to verify the communication performance of the simulation results.3.The development of the node communication prototype system of UV mobile ad hoc network is carried out.The overall architecture of node communication prototype system based on STM32 controller is given,and the corresponding system hardware circuit and software design are given.4.Through the debugging of each module of the system prototype and the overall prototype communication experiment,the communication performance of the system prototype is analyzed.Through the above work,the specific design scheme of UV mobile ad hoc network communication node is given,and the simulation results are verified through experiments,which lays a theoretical and experimental foundation for the realization of the UV ad hoc network communication system.Finally,through the development of the communication system prototype and the communication performance analysis of the node communication system,the feasibility of the communication system of the UV mobile ad hoc network node is further verified.It is of practical significance for the further study of the UV mobile ad hoc network communication.
