Target motion trail quality comprehensive evaluation method

Abstract

The invention discloses a target motion trail comprehensive quality evaluation method, and aims to provide a comprehensive quality evaluation method which is complete in evaluation index and independent of external information. According to the technical scheme, the method comprises the following steps: firstly, starting from a target motion trail, establishing a target motion trail comprehensiveevaluation index system based on time interval quality, point loss rate quality and track smoothness quality; secondly, extracting time, longitude, latitude and elevation information in the target motion trail data, and calculating a time interval quality index, a point loss rate quality index and a track smoothness quality index which reflect the quality of the target motion trail by utilizing the information; and finally, determining weighting coefficients of the three quality indexes based on an analytic hierarchy process, and calculating a target motion trail comprehensive quality evaluation index through a weighted summation mode. And thus, comprehensive evaluation of the target motion track quality is completed.

Description

technical field [0001] The invention relates to the quality assessment technology of target motion trajectory data in the field of information quality assessment, in particular to a method for comprehensively evaluating the quality of target motion trajectory. Trajectory Quality Evaluation Method Background technique [0002] The target movement trajectory is the movement route of the target within a period of time, which is formed by connecting a series of discrete observation points. The target trajectory information generally includes information such as acquisition time, target location (longitude, latitude and altitude). Based on the target's motion trajectory, the analysis of the target's motion parameters and motion behavior can be realized. With the continuous development of surveillance technology, the trajectory information of the target can be obtained in many ways, such as civil aviation aircraft track monitoring based on secondary surveillance radar and ADS-B,...
