摘要
随着现代通信科学、计算机科学、空间科学、海洋科学、地球科学等学科在众多相关领域的交叉研究和集成应用的迅速发展,人们能更多地利用电波在电离层中的传播特性,来完成远距离通信、超视距探测、大范围导航等活动,因此电离层对人类生产与生活的影响也日益突出。同时,由于电离层自身结构的复杂性,导致对其模型的刻画和预测带来了诸多不便和较大的误差。为了能更好的利用电离层,进一步研究电离层模型显得尤为重要。研究适合我国电离层的特点的电离层模型,重点针对模型的相关参数进行了仿真和讨论。首先分析了我国电离层的特点和选择了一种较适合的研究方法;然后选取了一组测量数据,并根据数据特点建立了一个统计模型;最后利用Matlab对模型的相关参数进行仿真实验,还与IRI模型比较,探讨了误差情况。
With explosive growth and integration of many interfacing discipline,such as communication,computer science,space science,marine sciences,geosciences and so on,people have made the most use of the ionosphere to establish long distance communications,over-the-horizon detection,large-scale activities such as navigation,ionosphere and the human impact on the lives of production also have become increasingly prominent.At the same time,due to the ionosphere to the complexity of their structure,leading to the characterization and prediction model has brought a lot of inconvenience and greater error.To be able to make better use of the ionosphere,and further study the ionosphere model it is particularly important.Suited to China's ionosphere on the characteristics of the ionosphere model,focused on the model of the relevant parameters of the simulation and discussion.China's first analysis of the characteristics of the ionosphere and choose a more appropriate method and then select a set of measurements and data features based on the establishment of a statistical model and finally the use of Matlab model of the relevant parameters simulation,And the IRI model,the circumstances of the error.
