Abstract

The characteristics of electromagnetic environment are the comprehensive characteristics formed by the interweaving of all electromagnetic radiation sources in a specific region. The analysis of electromagnetic environment characteristics is the basis of studying the electromagnetic environment effect of electronic information system. The existing analysis of electromagnetic environment characteristics is mostly based on the statistical characteristics of time, space, frequency and energy domain, as well as the dynamic characteristics of electromagnetic environment of the antenna port of electronic information system. However, the above methods can not give clear results for the comprehensive characteristics of electromagnetic environment obtained by using group sensors. In this paper, with the help of information geometry theory, the sensing sensor in the electromagnetic space is equivalent to an entity, and its ability to measure the electromagnetic environment is equivalent to forming a virtual field distribution in the electromagnetic environment measurement space. Using the virtual field distribution to represent the comprehensive characteristics is a new way to describe the changes of the characteristics of electromagnetic environment.
