A Secondary Surveillance Radar Data Analysis Technique Based on Geometrical Method

摘要

Due to the influence of special topography and meteorology conditions, the southwest ATC secondary surveillance radar has a unique characteristic which consists of a complex interference condition and a difference in data character compare with other areas. In order to analyze the blind area of the radar coverage and the surveillance of unreasonable target movement in this area, a radar target data analysis technique based on geometrical method is proposed in this paper. The data analysis technique consists of a horizontal position discrimination region method and a vertical altitude discrimination interval method. The technique can be implemented by the air traffic control department with a rational analysis of critical data components in the radar data. Therefore, by using such technique to achieve the purpose of improving the capability of critical data monitoring and maintenance, providing reasonable issue detection, and to ensure the safety of civil aviation operation.
