广域动态频谱态势基础理论与关键技术研究

Electromagnetic spectrum is an important national strategic resource and the sixth-dimensional battle space in the information age. With the development of mobile Internet, Internet of things and the electromagnetic spectrum war, the problems of spectrum resource shortage and spectrum security have become more critical and important, and the electromagnetic environment has been increasingly complex. It is urgently necessary to transform the traditional "static" management mode and implement the flexible spectrum sharing, the fine spectrum regulatory and the scientific spectrum decision. Spectrum situation is currently in its infancy, which is the most promising research direction of the transformation of spectrum resources and space to "dynamic" management. There are many challenging basic theories and key technical issues which need to be studied deeply and systematically. To solve the contradiction on spectrum situation awareness between breadth and precision, the contradiction on situation prediction between dynamic and accuracy, and the contradiction on spectrum situation utilization between complexity and efficiency, this project intends to study spectrum situation theoretical model, wide domain spectrum situation awareness, multi-dimensional spectrum space situation generation, efficient spectrum situation utilization, etc., and build a scientific demonstration platform. In order to form a more complete theory of spectrum situation and breakthrough core technologies, this project efforts to solve the key theoretical issues of the spectrum situation mathematical model, large-range "state" sensing, multi-dimensional "tendency" generation and "situation" efficient utilization, and then make positive contributions to efficient sharing of future 5G network spectrum resource, secure management of state radio, advantages generation of army electromagnetic spectrum battle.
