The invention discloses an anti-interference measuring system for space distribution of environmental-electromagnetic radiation of a mobile communication base station. The anti-interference measuring system comprises a mobile-communication emergency communication system, an anti-interference measuring device and a simulated user terminal, wherein the anti-interference measuring device is arranged on a testing path between the mobile-communication emergency communication system and the simulated user terminal. The invention also discloses an anti-interference measuring method for the space distribution of the environmental-electromagnetic radiation of the mobile communication base station based on the anti-interference measuring system. The invention has the advantages that various types (2G, 3G, 4G and the like) of base stations can be simulated to shield interference of reflection, diffraction and scattering of various electromagnetic radiating sources and self signals and realize accurate measurement of the electromagnetic radiation level of the three-dimensional space of the base station. The development and the application of the invention are beneficial to obtaining the space distribution condition of the environmental-electromagnetic radiation level of various base stations and provide basic data for prediction and analysis of the influence of the electromagnetic radiation environment of the base stations.
Description
technical field [0001] The invention belongs to the fields of environmental electromagnetic radiation testing, electromagnetic compatibility, and electromagnetic anti-interference, and in particular relates to an anti-interference measurement system capable of performing spatial distribution test on the environmental electromagnetic radiation level of a mobile communication base station and a measurement method thereof. Background technique [0002] Electromagnetic radiation pollution has become the fourth largest pollution after air, water and noise pollution. Mobile communication base stations are the main source of electromagnetic radiation in cities, and can reach every 0.09km in densely populated urban areas. 2 There is only one base station, and the public is very concerned about the electromagnetic radiation generated by the base station antenna. Correspondingly, the environmental monitoring department has also carried out a lot of monitoring work. [0003] As the co...
