Problems solved by technology

[0003] At present, the operation analysis based on performance data under the new concept of air traffic operation and the application of new technologies is still blank in our country. Because radar data has four-dimensional characteristics with high precision, it is different from other data performance analysis, and the method is independent. Therefore, the current domestic There is no track fitting analysis method based on radar track data

Abstract

A fitting analyzing method based on radar track includes the following steps: (1) reading analyzed radar data; (2) transforming the data of step one to create point spatial data; (3) data fusing on spatial radar track point data into track spatial data with service attribute; (4) analyzing precision holding ability in horizontal direction of track-flight path airspace and area half width of flightpath resource required by special track holding precision. The method statistically analyzes holding precision of the track in the horizontal direction and discrete point probability and density distribution by track fitting on radar track points, constructs the foundation of decision-making based on performance data analysis, and provides quantized index for airspace management.

Description

technical field [0001] The invention relates to a radar track fitting analysis method, in particular to a track keeping precision analysis based on radar track data, an aircraft density analysis in a specific airspace, and an analysis method for required airspace resources. Background technique [0002] With the rapid development of our country's national economy, the volume of air traffic continues to grow, making it difficult for the existing air traffic management system and technology to meet the needs of development. In order to promote the sustainable development of air traffic and solve the bottleneck of limited airspace resources, ICAO is constantly introducing new concepts and technologies for air traffic operations. [0003] At present, the operation analysis based on performance data under the new concept of air traffic operation and the application of new technologies is still blank in China. Because radar data has four-dimensional characteristics with high preci...
