Embodiment 1

[0048] Before carrying out this method, it is necessary to build the electromagnetic environment data acquisition equipment of the civil aviation station to realize accurate and comprehensive automatic collection and recording of the characteristic parameters of the civil aviation station. Among them, the characteristic parameters of the civil aviation station include:

[0049] Signal business: radio communication (ground-air communication equipment, ground-ground communication equipment), radio navigation (heading / glide / pointer instrument landing system, omnidirectional beacon / range finder, non-directional beacon), radio surveillance (one / Secondary integrated radar, secondary radar, field surveillance radar, Automatic Dependent Surveillance-Broadcast System ADS-B).

[0050] Signal parameters (frequency domain): ITU parameters (frequency, frequency difference, level, field strength, occupied bandwidth, occupancy, modulation degree), modulation method, symbol rate;

[0051] Si...

Abstract

The invention discloses a method for assessing the electromagnetic environment quality of a civil aviation station based on a comprehensive application scenario, including the following contents: real-time acquisition of electromagnetic environment characteristic parameter data of a civil aviation station in an actual application scenario; automatic and new application scenario of a civil aviation station The electromagnetic environment reference database is used for data correlation analysis; the quality assessment and analysis report of the electromagnetic environment of civil aviation stations in this application scenario is obtained. Through the establishment of the electromagnetic environment reference database of civil aviation stations in the application scenario, the simulated or actually acquired characteristic parameter data of each civil aviation station can obtain the real situation of the electromagnetic environment quality of each civil aviation station during use; and through the data of the reference database Real-time comparison can be used to actively and effectively warn when the electromagnetic environment quality of each civil aviation station is deteriorating, and the specific data that causes the deterioration of the electromagnetic environment quality of each civil aviation station is obtained, and the electromagnetic environment of each civil aviation station is given. Quality assessment and analysis report to ensure the safety of civil aviation flight.

Description

technical field [0001] The invention relates to an electromagnetic environment quality assessment method, in particular to an electromagnetic environment quality assessment method for civil aviation stations based on comprehensive application scenarios. Background technique [0002] In civil aviation airports and surrounding areas, more and more infrastructure and equipment are being built for air traffic control and civil aviation stations, and the electromagnetic environment is becoming more and more complex. Civil aviation stations themselves are often interfered by other frequency interference between stations within the civil aviation system and outside. However, there are no professional electromagnetic environment quality assessment tools or methods for civil aviation stations in various application scenarios, and the construction environment of civil aviation stations is not clear, and it is impossible to effectively grasp the electromagnetic environment data of civil...
