Centralized Multi-radar System Tracking Technology To Study

In the target-tracking field of information fusion, centralized-system take a important role because of it's good tracking-precision and rapid track-origination. Centralized-system have complex structure and need a great deal of calculations,But by a series of advanced senseor integrated conception,it have strong vitality. All modules in the tracking algorithm of multi-radar centralized-system be studied in this paper.The main work are outlined as followed:Firstly,the basic theory of information-fusion is systemly studied. The data-fusion's intention,significance, basic principle,content,evolution and application are systemly researched.Based on the main content,the trait and key-matter of multi-radar centralized-system are analyzed.Secondly, By studying the space-calibration,time- calibration and spot-track'unite, the spot-track of multi-radar centralized-system be importantly discussed how to deal with and the tracking problem of multi-radar centralized-system be turned single radar multi-target tracking matter.In the spot-track'unite,the clustering idear of mode-identify is used to settle the problem and the calculation load is be reduced. The selection of clustering radius is studied and the rationality of parameter is validated.The notion of right-clustering-probability is put forward and is used to evaluate the clustering quality of some clustering rule.Thirdly,the theory of single radar multi-target tracking (kalman filter algorithm ,dynamic target model, track's origination and expiration,the form of tracking-door and association algorithm)is dicussed,which is turned the basis of multi-radar centralized-system's tracking algorithm.Finally,the algorithm model of six modules(space-calibration, time-calibration,spot-track'unite, track's origination and expiration, the form of tracking-door and association algorithm) are founded.The effect of some modules to tracking result are studied and their intimated results are gained. The intimation resultof centralized-system and distributed-system are compared in the end.
