However, many factors affecting the field strength, such as path, terrain, sunshine, and climate, increase the computational complexity, which greatly increases the difficulty of establishing an accurate prediction system. After persistent research by researchers in recent years, the ITU\u2010R P.1546 model has gradually become a point\u2010to\u2010surface forecasting method for ground services recommended by ITU for ground operations in the frequency range of 30\u2009MHz~3000\u2009MHz. In view of the characteristics of electromagnetic signal propagation in mountainous environment, the influence of diffraction is also considered in this paper. Based on more accurate scene information such as actual terrain, the prediction calculation of electromagnetic signal propagation in a mountainous environment is proposed by using the corrected ITU\u2010R P.1546 model. In addition, the influence of the actual terrain is taken into account to correct the relevant parameters, and the predicted results are compared with the measured data. The results indicate that field strength prediction results of the ITU\u2010R P.1546 model based on the diffraction effect correction proposed in this paper in specific physical areas have better performance than those of the traditional ITU\u2010R P.1546 model. Among them, the determination coefficient between the measured data and the predicted results is 0.87, the average error is 5.097\u2009dB<jats:italic>\u03bc<\/jats:italic>V\/m, and the root mean square error is 6.6228\u2009dB<jats:italic>\u03bc<\/jats:italic>V\/m, which proves that the ITU\u2010R P.1546 model based on the corrected model is effective in the prediction of electromagnetic field intensity in the actual mountainous environment.<\/jats:p>","DOI":"10.1155\/2021\/8136833","type":"journal-article","created":{"date-parts":[[2021,9,13]],"date-time":"2021-09-13T18:22:55Z","timestamp":1631557375000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Study on the Diffraction Correction Prediction of Electromagnetic Field Intensity Based on the Method of Estimating Aerial Access Network Signal"],"prefix":"10.1155","volume":"2021","author":[{"given":"Jialuan","family":"He","sequence":"first","affiliation":[]},{"given":"Zirui","family":"Xing","sequence":"additional","affiliation":[]},{"given":"Qiang","family":"Wang","sequence":"additional","affiliation":[]},{"given":"Feihong","family":"Wu","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2591-9529","authenticated-orcid":false,"given":"Fuyong","family":"Lu","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,9,13]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"crossref","unstructured":"OstlinE.
