车载式选频测量(30 MHz~6 GHz)在城市电磁环境水平监测的应用

Abstract

Abstract: Objective: To measure the level of urban electromagnetic environment more efficiently and accurately and master the composition of electromagnetic environment. Methods: The DZER100 vehicle-mounted fast frequency selection measurement system was developed jointly with Chengdu Dot Matrix Technology Co., LTD. The full-band scanning time of the system was 300 ms under the condition of 30 MHz-6 GHz frequency band and 100 kHz resolution. With a driving speed of 60 km/h and a distance of 5 m between measuring points, the total field intensity, spectrum and electromagnetic environment of specific frequency band of each measuring point can be effectively obtained. Results: 14 393 effective point data were obtained for 5.3 km² area. Through automatic analysis of system data, the average electric field intensity of the whole area was about 1.23 V/m, and the ratio of 0 V/m-2 V/m reached 87.411%. The average value of standard ratio was 1.41%, and only 0.24% of the sites accounted for more than 20%. Through the spectrum visualization analysis function, the spectrum composition of the focus point and the contribution of the focus frequency band can be quickly grasped. Conclusion: The vehicle-mounted frequency selection measurement (30 MHz-6 GHz) can realize the simultaneous measurement of the total field intensity and spectrum of each point, which effectively solves the remaining pain points caused by the use of non-frequency monitoring instruments. The obtained data amount is far more than that of the traditional grid measurement method, and the data are more representative, which can reflect the electromagnetic environment in the region more comprehensively. The vehicle-mounted frequency selection measurement can meet various requirements such as the measurement and evaluation of the overall level of regional electromagnetic environment and the analysis of the composition of the electromagnetic environment source terms, and provide more detailed and accurate basic data for the management of electromagnetic environment through visualized data.
