Problems solved by technology

Because if a certain traffic situation has radar signal repetition or overcrowding on the radar screen, it will make it difficult for controllers to quickly identify different radar signals and identify flight conflict points, thereby increasing the control workload and ultimately reducing the air traffic system. Capacity
However, with the rapid development of air transport, the complexity of air traffic situation is also increasing sharply, and there is no report on the complexity of air traffic display in domestic and foreign research.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] The air traffic display complexity measurement method based on the network model includes the following specific steps, such as figure 1 Shown:

[0016] Step 1. Establish a multi-dimensional index system from the perspective of the network: according to the basic characteristics of air traffic operations, select node degree, edge number, connection rate, edge growth rate, aggregation coefficient, and network structure entropy from the more general network topology feature description indicators , as an index system for air traffic display complexity assessment.

[0017] Step 2. Receive and process radar data: Receive radar data every 4 seconds, extract aircraft target number and aircraft coordinates, speed, heading and other key navigation information; take every 1 minute as an example to perform coarse-grained processing on the original data, a...

Abstract

The invention discloses a measuring method for air traffic display complexity. The method comprises the following five steps: firstly, establishing an index system for air traffic display complexity evaluation; secondly, accessing a radar track to an air traffic control system in real time, and extracting the information of an aircraft position at each moment; thirdly, establishing a network model corresponding to the current moment on the basis of the aircraft position and the mutual distance relationship thereof; calculating each network index value according to the established index system; and finally, forming a complexity vector. The method disclosed by the invention can be used for objectively evaluating the display complexity on a radar display screen in multiple dimensions, the method is not influenced by human factors, the occupied capital is less, the evaluation method is simple and easy, and the evaluation result is easy to be understood.

Description

technical field [0001] The invention relates to the field of air traffic management, in particular to a method for measuring the complexity of air traffic display based on a network model. Background technique [0002] In air traffic operations, controllers generally try to maintain a large horizontal separation as much as possible to avoid the situation of aircraft getting together. Because if a certain traffic situation has radar signal repetition or overcrowding on the radar screen, it will make it difficult for controllers to quickly identify different radar signals and identify flight conflict points, thereby increasing the control workload and ultimately reducing the air traffic system. capacity. However, with the rapid development of air transport, the complexity of air traffic situation is also increasing sharply, and there is no report on the complexity of air traffic display in domestic and foreign research. Therefore, mapping the air traffic situational structur...
