Description

technical field [0001] The invention belongs to the technical field of civil aviation traffic control, and in particular relates to a time-series meteorological scene intelligent recognition system in a terminal area. Background technique [0002] Meteorology is an environmental characteristic of aircraft operation, which will have a significant impact on airspace and ground flight operations. Severe convective weather affects the capacity and flow of the airspace, and flights will be diverted, delayed, and canceled due to a series of traffic control strategies issued by the air traffic control department, such as ground waiting and crossing restrictions. According to the impact of weather on the operation of the terminal area, the terminal area can be identified as different operation scenarios to represent the different types and degrees of interference and influence brought by the weather on the operation of the terminal area. The meteorological scene recognition in the ...

Problems solved by technology

However, these techniques do not consider the time-series changes of meteorological impacts, and can only give instantaneous meteorological impact scenarios

However, air traffic flow management strategies, controller work shifts, and historical flight operation analysis are all carried out in units of hours. The existing meteorological scene recognition system in the terminal area cannot fully meet the needs of the civil aviation traffic control field, and the actual reference value is relatively low. weak

Moreover, the previous systems lacked a reasonable dimension reduction or information processing scheme, and it was difficult to fully utilize ultra-high-dimensional radar weather information.
