With continuous popularization of public infrastructures and daily electronic instruments, such as electric power communication systems and household appliances, electromagnetic radiation sources have increased sharply in the geographic environment, which leads to increasingly serious electromagnetic radiation pollution. Thus, it is significant to monitor, evaluate, and analyze the electromagnetic radiation condition and explore its changing law in the environment. However, the traditional monitoring method can only detect anomalies within certain frequencies in the fixed stations. To fill this gap, this research first develops a vehicle\u2010mounted electromagnetic environment monitoring system to collect both spatial positioning data and electromagnetic data of the whole frequency range. The acquired data are then used to construct the location\u2010based frequency\u2010intensity curve to reflect the variation of electromagnetic radiation at different frequency ranges. On this basis, a curve similarity measurement method is introduced to analyze the similarity of different curves, which is effective to diagnose time\u2010varying sources from both global and local perspectives. This research provides a real\u2010time mobile monitoring method, which is significant to know the dynamic variation of local electromagnetic environment and promotes subsequent comprehensive geographic analyses.<\/jats:p>","DOI":"10.1155\/2021\/8819402","type":"journal-article","created":{"date-parts":[[2021,11,16]],"date-time":"2021-11-16T18:05:38Z","timestamp":1637085938000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Detecting Electromagnetic Geographical Environment Changes Based on the Frequency\u2010Intensity Curve"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7134-8328","authenticated-orcid":false,"given":"Yi","family":"Huang","sequence":"first","affiliation":[]},{"given":"Mengyi","family":"Wang","sequence":"additional","affiliation":[]},{"given":"Qianqian","family":"Qiu","sequence":"additional","affiliation":[]},{"given":"Lizhi","family":"Miao","sequence":"additional","affiliation":[]},{"given":"Haiping","family":"Zhang","sequence":"additional","affiliation":[]},{"given":"Jiarui","family":"Qin","sequence":"additional","affiliation":[]},{"given":"Xiangqiang","family":"Min","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6980-5208","authenticated-orcid":false,"given":"Yehua","family":"Sheng","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,11,16]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10712-015-9351-1"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1029\/2011GL049572"},{"volume-title":"Electromagnetics with Applications (Fifth Edition)","year":"1999","author":"Kraus J.
