This paper presents two fuzzy track correlation algorithms with double threshold applying to dis tributed multisensor data fusion.In the paper,composition of fuzzy element sets,selection of membership function,dynamic assignment of weight vectors,track mass design,multivalency processing methods,fuzzy double threshold track correlation criterion and fuzzy classical assignment problem are discussed.Moreover,the algorithms are com pared with two classical methods through simulation.The simulation results show that the performance of the fuzzy double threshold track correlation algorithms is much better than tha of the classical methods in dense multitarget environments,more cross,split and maneuvering track situations.Under the above situation their correct correlation rates are improved about 35 percent over the classical methods.
