Study On Dynamic Use Technology Of Electromagnetic Resources Based On Battlefield Frequency Data

With the development of army informatization,the amount of informationized equipment grows rapidly.Then the need of electromagnetic resource also grows.The request of spectrum bandwidth and time delay grows at the same time,which aggravated the problem of electromagnetic resource shortage.Now,the mechanism of electromagnetic resource utilization is the pre-project based mechanism,which is inefficient.To solve the problems brought by the pre-project based mechanism,the study on the dynamic utilization technology of electromagnetic resource is important.This paper aims to realize the efficient utilization of battlefield electromagnetic resource.The main work is as follow:Firstly,the obtaining of the battlefield spectrum data is studied.The energy based signal detection and the cooperation detection mechanism are adopted.The reliably universe spectrum data obtain is realized by laying limited spectrum detection equipment,through the spectrum sample data supplement technology.The experiment based on the multiple USRP equipment shows that the proposed approach could obtain the battlefield spectrum data with low cost.Secondly,the location of the battlefield spectrum equipment is studied.The energy correlation based battlefield spectrum equipment location algorithm is proposed.The characteristic of the algorithm is that the signal power of battlefield spectrum equipment and the decline regularity of the signal would not be need.To solve the problem brought by the complex multiple routing and decline,the location algorithm based on threshold setting is also proposed.The result of experiment shows that the proposed approach could solve the location problem wel.Thirdly,to solve the inefficient problem of the static pre-project based mechanism,the technology of battlefield dynamic utilization technology of electromagnetic resource is studied,including the frame structure of the dynamic electromagnetic resource utilization,the efficient distribution of battlefield spectrum data,and the technolo gical process of battlefield dynamic utilization of electromagnetic resource.
