Self-adaptive adjusting method and device for unit window in controlled airspace

Abstract

The invention discloses a self-adaptive adjusting method and device for a unit window in a controlled airspace. The self-adaptive adjusting method comprises the following steps: determining the related flight path judgment range when an observation point is detected in the controlled airspace, wherein the related flight path judgment range comprises the unit window with the observation point and other unit windows adjacent to the unit window with the observation point; determining the adjustment scheme of the unit window (narrowing the unit window) if it is judged that no system flight path relevant to the observation point exists in the related flight path judgment range and at least on system flight path exist in the unit window with the observation point; and redividing the controlled airspace according to the determined adjustment scheme of the unit window. Because the unit window can be adjusted in a self adapting way according to the condition of the controlled airspace, the leakage of the correlation can be avoided, the amount of calculation can be reduced, the correlation judgment efficiency can be improved, and more calculation resources of the system can be saved.

Description

technical field [0001] The invention relates to the general aviation communication technology, in particular to the technology of carrying out system track association on air flying targets for tracking and analysis. Background technique [0002] In recent years, with the rapid development of the aviation industry, various aviation flight activities such as civil aviation passenger transport, cargo and general aviation flight activities have become more frequent and intensive. [0003] In order to ensure the safety and order of aviation flight, it is necessary to monitor and control the flight targets in the airspace and implement air traffic control. At present, the air traffic control system with radar as the detector is the main technical means. It receives the flying target data detected by the radar reflection wave, analyzes and comprehensively processes it, establishes the system track for each flying target, and The state of the flying target is intuitively displayed...

The secondary code is unique in the same control area, and may be repeated in different control areas

[0022] The inventors of the present invention have found that the size of the unit window in the controlled airspace directly affects the size of the relevant track judgment range, while the unit window of the controlled airspace used in the judging method for the correlation between the observation point and the system track in the prior art The size is fixed, and the side length is usually set at 10-20km, so the relevant track judgment range is also fixed

However, nowadays aviation flight activities are becoming more and more frequent, and the maneuverability of aviation aircraft is improving day by day. There are some problems in the size of this fixed unit window: if the window is too large, the range of the above-mentioned relevant track judgment will be correspondingly too large, and it is necessary to make a correlation judgment There may be a lot of system tracks, resulting in a large amount of calculation, low judgment efficiency, and excessive system computing resources; if the window is too small, under high maneuverability of the target, it may cause leakage correlation, that is, the system track related to the observation point is not accurate. It exists within the judgment range of the relevant track, but exists in the controlled airspace, resulting in the observation point not being associated with its related system track, thus losing the target
