Research on the Distribution of the Regional Electromagnetic Radiation Based on the Interpolation Methods

As the electromagnetic environment becomes more complex, it is particularly important to objectively evaluate the electromagnetic environment in urban areas. Traditional electromagnetic radiation monitoring methods still remain at the stage of monitoring and processing at independent stations. It is impossible to obtain the continuous data of regional electromagnetic radiation. However, spatial interpolation can reasonably estimate unknown values from data observed at known locations, finally get the complete data of electromagnetic field and predict the distribution of electromagnetic radiation in the region of interest. In this paper, the interpolation results are quantitatively evaluated by the criteria of mean error and root mean square error in three methods: Inverse Distance Weighted (IDW), Radial basis function (RBF) and Ordinary Kriging.
