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 the rapid development of the interdisciplinary research and integrated application of modern communication science, computer science, space science, marine science and earth science in many related fields, people can make more use of the propagation characteristics of radio waves in the ionosphere to complete Long-distance communication, over-the-horizon detection, wide range of navigation and other activities, so the ionosphere on human production and life are also increasingly prominent. At the same time, due to the complexity of the structure of the ionosphere, many inconveniences and large errors are brought about by its modeling and prediction. In order to make better use of the ionosphere, further study of the ionospheric model is particularly important. The ionospheric model that suits the characteristics of ionosphere in our country is studied. The relevant parameters of the model are simulated and discussed. Firstly, the characteristics of the ionosphere in our country are analyzed and a more suitable research method is selected. Then a set of measurement data is selected and a statistical model is established according to the characteristics of the data. Finally, the simulation experiments are carried out on the relevant parameters of the model Compared with the IRI model, the error situation is discussed.
