| Based on shore-based multi-radars,the offshore radar ship surveillance system can not only dynamically monitor the situation of ships at sea and manage the traffic situation of ports,but also play a role in rescue and rescue at sea and combating crimes at sea,thus contributing to the protection of Marine resources.Therefore,if we want to ensure the safety of the adjacent sea and further broaden the field of offshore regulation,we must make full use of this method.When this system is used to monitor the ship’s navigation,the ship’s track needs to be tracked first,and to do this work well,the ship’s complete track information must be ensured,so as to obtain a good track tracking effect.This study not only study the initial algorithm of ship trajectory tracking,but also study the display control of system.Aiming at the deficiency of traditional heuristic method in the initial part of aircraft tracking,a method of using machine learning algorithm training model to classify the track is proposed,and the possible missing alarm problem is studied and optimized.In addition,the software design of the display control subsystem mentioned above is completed,and the classifier algorithm is tested in this system.The main contents and results of this study are as follows:(1)This thesis introduces the design of the tracking starting algorithm and the offshore ship radar monitoring system with the focus on the database,architecture and communication between modules of the monitoring system.(2)The idea of using a classifier is proposed to improve the algorithm of the initial part of track tracking.It includes the principle of classifier,construction flow,processing flow and so on.Through simulation experiment,compared with the traditional heuristic rule method,the algorithm of initiation is improved,and the ability of discovering target and suppressing false track is improved.(3)Classifier method,found problems in the practical application include: first,the algorithm for the target volume sliding sideways p situation has not completed the modeling of the operation,the leakage measurements at a police case,will verify the serious influence track starting performance,especially when the system is in low case detection rate,track initiation performance will be greatly weakened.In this thesis,an optimization scheme is proposed to effectively suppress the false trajectory and complete the target track starting work.(4)Taking the offshore ship radar monitoring system as the research object and the requirement of its display control system as the research content,the software design of the display control system is completed.At the same time,based on the field environment of the monitoring system and its display control system,make this thesis has a good condition for evaluating the application performance of the algorithm in the century,and also proves the optimization and improvement algorithm mentioned in this thesis,so that its comprehensive performance meets the relevant requirements both in the experiment and in the actual application. |
