摘　　要：由于现有的简单的转移概率矩阵会导致跟踪精度不高,复杂的转移概率矩阵会导致跟踪时间过长,难以满足三维空间中机动目标跟踪要求。针对转移概率矩阵的设计问题,从机理分析入手,提出了一种基于隶属度函数的模型转移概率矩阵设计方法,并对三维交互式多模型算法进行了改进完善。仿真结果表明,依据隶属度函数修正转移概率矩阵的方法有效提高了三维机动目标的跟踪精度。Due to the low tracking accuracy of existing simple transition probability matrices and the long tracking time of complex transition probability matrices,it is difficult to meet the requirements of maneuvering target tracking in threedimensional space.Aiming at the design problem of transition probability matrix,starting from mechanism analysis,a model transition probability matrix design method based on membership function is proposed,and the three-dimensional interactive multi model algorithm is improved and perfected.The simulation results show that the method of modifying the transition probability matrix based on the membership function effectively improves the tracking accuracy of three-dimensional maneuvering targets.
