Abstract: In this paper，a fuzzy interacting multiple model is developed to solve data association problem of a new target of MHT multitarget tracking.A fuzzy IMM is introduced to deal with the data association problem of a new target.This can improve the track precision and the time efficiency of the algorithm.The degree of membership is adopted to express membership relation between every model and a new target，an optimal model to tract new target is picked out by the degree of membership.The simulation results indicate that the measure can improve the time efficiency of algorithm.

摘要： 研究了基于模糊交互式多模型算法解决多假设多目标跟踪中的新目标数据相关问题。使用模糊交互式多模型算法处理新目标的数据相关问题，能够提高跟踪精度、时间效率。用隶属度表示每个模型与所跟踪新目标的隶属关系，根据隶属度选择最佳的模型对新目标进行跟踪。仿真结果表明，该方法不仅能够处理新目标的数据相关，同时又能够提高算法的时间效率。
