Description

Technical Field

[0001] The present invention relates to the technical field of radio interference, and in particular to an aviation radio interference analysis method based on QAR data. Background Art

[0002] The safe use of aviation radio frequencies is the premise and foundation of civil aviation flight safety. In recent years, with the rapid development of radio technology, the number of radio stations has increased, and the probability of civil aviation radio frequencies being subject to radio interference has continued to increase. Radio interference can cause the aircraft's onboard GPS, ADS-B, radio altimeter and other systems to fail to operate normally, and trigger false GPWS warning events, causing flights to go around or terminate approaches, make alternate landings, etc., which has an adverse impact on the normal and safe flight. This application is based on the QAR (Quickaccess recorder) data collected and analyzed by the civil aviation flight quality monitoring base station (hereinafter referred to as the "bureau base station"), and conducts aviation radio interference analysis research, providing aviation radio interference analysis data support services to the industry and beyond.

[0003] QAR is an important airborne electronic device that records aircraft flight parameters. It can continuously record raw information data for up to 600 hours of flight, and can collect hundreds or even thousands of different flight parameter data at the same time. QAR data is important flight data for flights, and is the mirror data of the onboard black box. It is often used for post-flight technical analysis, engine health analysis, flight safety incident investigation, etc. It is an important data warehouse for flight quality analysis, operation quality analysis, and aircraft health management. The flight QAR data currently owned by the Institute of Aviation Science is complete and covers a wide range.
