Method and system for monitoring interference signals in aviation radio signal transmission

Abstract

The invention relates to the field of radio transmission, in particular to a method and system for monitoring interference signals in aviation radio signal transmission, and the method comprises the steps: 1, continuously carrying out the collection of radio frequency sweeping spectrum data; step 2, signal extraction is carried out by using a signal-noise separation threshold line, signals of a monitoring frequency band are extracted from the collected frequency spectrum data, and the monitoring frequency band comprises a frequency modulation broadcast frequency band and an aviation communication frequency band; step 3, monitoring each signal in the aviation communication frequency band by using a signal residence time monitor so as to find an abnormal signal; and step 4, if the abnormal signal of the aviation communication frequency band is found in the step 3, calculating the correlation degree between the abnormal signal and all other signals in the monitoring frequency band so as to detect the interference source. According to the invention, the problems of slow processing speed, high investment cost, long interference searching time and untimely supervision of traditional aviation radio supervision are solved, and reliable transmission of aviation radio signals is guaranteed.

Description

technical field [0001] The present invention relates to the field of radio signal transmission, in particular, to a method and system for monitoring interference signals in aeronautical radio signal transmission. Background technique [0002] With the rapid development of radio and related technologies, it has brought great convenience to people's lives, but at the same time, it has also brought a lot of influence to radio services in related frequency bands in the process of use. In particular, the current civil society aviation frequency band communication is often affected and interfered by abnormal radio, which seriously threatens the flight safety of civil aviation passenger aircraft and passengers. [0003] The safe use of the radio frequency dedicated for civil aviation is an important prerequisite for ensuring the safety of civil aviation flight, which is directly related to the safety of life and property of civil aviation passengers and the people, as well as the o...
