Research On The Construction Of Electromagnetic Information Database And The Application Of Interpolation Algorithm In Geographic Environment

With the progress of the times and the rapid development of communication technology,electromagnetic waves have been like water and air in every corner of human life.In recent years,the research on the electromagnetic environment produced by the interaction of geographical environment and electromagnetic field has become more and more important,and the research on the reconstruction and visualization of electromagnetic information in the electromagnetic environment is the essential part of the research.In the reconstruction and visualization of electromagnetic data information,it is particularly important for the classification system,acquisition means,organization method and fusion technology of electromagnetic data.The purpose of this essay is to study the data base of electric field related to the electromagnetic environment,so as to reduce the unnecessary computing time in the study of the electromagnetic environment.The main reference data in this essay are the array antenna pattern database and the antenna in a different environnment.Subsequently,it is proposed that the model based parameter estimation interpolation algorithm(MBPE)is applied in the reconstruction of electric field data,so as to make up for the shortage of electromagnetic data.This paper first introduces the significance of the research on the electromagnetic geographic environment and the research and development of all countries in the era of rapid development of various communication devices.In the study of the electromagnetic environment,in the face of such huge data information,"interdisciplinary" draws on the concept of "database" in computer science and proposes to build a number of databases on electromagnetic information.In this report,we have preliminarily built the electric field database of the antenna array and antenna in different environments.In the process of building the electromagnetic information database,this paper focuses on the detailed discussion and Research on the acquisition process of two kinds of database data and information.In the last section,in view of the limited data in the database and the amount of electromagnetic data in the electromagnetic geography environment,the number of electromagnetic data is a huge reality,and other technical means are put forward to collect and process the existing electromagnetic data.The interpolation technology is particularly important for the supplement of electromagnetic data in the electromagnetic environment.In this report,the MBPE interpolation algorithm is applied to the electromagnetic environment,especially when the study area is small.When the precise interpolation is needed,the MBPE interpolation algorithm in electromagnetic numerical calculation has better interpolation effect than the existing spatial interpolation algorithm.In addition,the research of this subject can not only reduce the complex and redundant computation of electromagnetic data in the study of electromagnetic environment,but also for the national key project "holographic map acquisition and location information polymerization technology",the national key project of the research group,"acoustic and optical electromagnetic data acquisition and fusion" The research task of "law" provides help for the classification system,acquisition means,organization method and fusion technology for the construction of the dynamic scene of holographic map.
