Efficient Accurate Modeling Research Of Electromagnetic Wave Propagation Loss In Typical Landforms

In this paper,the typical geomorphic radio wave propagation loss is discussed through the establishment of efficient and accurate simulation model,combining closely with the application background of electromagnetic compatibility problem between systems,and the paper reveals the general rule of different geomorphological radio waves propagation loss.At the same time,according to the simulated data,we build a statistical model of typical geomorphic radio wave propagation loss,which can provides data support for the analysis of the electromagnetic compatibility problem between systems.This paper introduces some classical radio wave propagation loss models,such as Hata model and so on.we find the classic model does not apply to this project needs,so it is necessary to establish a new model.By separating the simulation method,the typical geomorphic surface equivalent model is established,including flat open landscape such as concrete and weeds,and the plain,hilly landscape.In this paper,the main contents includes:1,We establish the accurate simulation model of communication vehicle(car shelter),ground environment and antennas in FEKO.2,Studying the rules of electromagnetic coupling between the antenna of the typical geomorphic.3,We can get radio waves propagation loss of different geomorphic by the simulation data of the coupling between the antenna,and analyze the influence of radio wave propagation.4,According to analyze the simulated and measured data,we verification the correctness of new methods and the model in this paper.5,we build a statistical model of typical geomorphic radio wave propagation loss.
