Research On Composite Tracking And Tracking Method Based On Multi-platform And Multi-objective

Along with the rapid development of modem technology and the demand of modern war,multi-sensor technology has become the hotspot in the maneuvering target tracking field.In the face of modern battle with the enemy flying high maneuverability and complexity of targets,in order to strike and defend effectively,we must combine organically multiple sensors information to accurately track.Based on tracking anti-ship missiles background,the paper mainly research multi shipboard radar sensor tracking missile.The tracking method and composite tracking of multi-platform tracking system as two aspects were discussed.Firstly,multiple target tracking theories are introduced,and analyze the tracking filter method.The target motion mathematical model which are commonly used are summarized and discussed,analyzed five kinds of filter algorithm,include KF,EKF,UKF,IMM and FTIMM,and has carried on the contrast.Secondly,weighting method,fixed method,independent sequential method which are based on statistical theory are discussed,and method for performance evaluation of track association is given.Again,based on the background of network centric warfare,introduce composite tracking algorithm.The composite tracking algorithm is composed of two parts,one is tracking fusion under common area,and anther is relay tracking in a blind area.This paper mainly discusses track fusion algorithm,including simple convex set,Bar-Shalom-Campo arithmetic and covariance crossing method,analysis the structural of relay tracking.Finally,the comprehensive simulation experiments are carried out.Based on the "snake" motor model,the tracking filter methods are simulation and analysis.By the correct rate of association,the weighting method,fixed method and independent sequential method are compared.Simple convex set,cross covariance and covariance crossing method are used for simulation experiment with associated successful route,the reliability of the algorithms are validated,and at the same time compared the accuracy of the algorithm.From the perspective of engineering application,the key of multi-target tracking are discussed in this paper,and certain reference value for engineering practice is existed.
