Construction and Assessment of Quality Evaluation System for Solving Target Motion Elements

Abstract

Target tracking is an important part of the anti-submarine warfare process of surface ships. In the process of target tracking, the four elements of targets are obtained through the target motion element solving, and the hit probability is calculated through the result. The solution results of the target motion elements are affected by many factors, such as battlefield situation, detection method, and solution model. In order to associate the separated factor, a quality evaluation system for solving target motion elements was constructed from the four aspects of completeness, availability, timeliness, and accuracy of the solved data. In order to minimize the total deviation, the analytic hierarchy method and entropy weight method were effectively combined to determine the index weight. The quality evaluation value of the target motion elements was obtained by weighted summation and compared with the simulation result of hit probability. The simulation results show that the error between the approximate hit probability and the actual hit probability calculated by using the solved mass is less than 9.2%. The evaluation system constructed in this paper can effectively combine all information, reasonably and fully express the hit probability, and is conducive to the decision-making of the engagement.
