摘　　要：为借助飞机姿态角提高跟踪性能,在一种改进的IMM算法基础上,一方面,对飞机处于各运动模型时姿态角的变化规律进行分析,利用姿态角求解角度变化率来实时更新模型集;另一方面,通过在姿态角滤波过程中加入机动检测和极性判别,提升了离散点过程滤波器的输入量测值的精度。之后,提出了一种基于飞机姿态角辅助的交互式多模型跟踪算法。仿真验证了该算法的精度。In order to improve the tracking performance by use of the pose-angle of plane,an improved Interactive Multi-Mode（IMM） algorithm was studied.The changing pattern of the pose-angle when the plane was at different motion mode was analyzed,and the angle change ratio was calculated based on the pose-angle to update the model set in real time.On the other hand,maneuvering detection and polarity judgment were introduced into the process of pose-angle filtering,and thus to improve the measurement accuracy of the input of the discrete-point process filter.And then an IMM tracking algorithm aided by pose-angle of plane was proposed.Simulation demonstrated the accuracy of this algorithm.
