| 中文摘要 |
| 针对转弯机动目标跟踪, 提出了一种两层交互多模型(IMM)跟踪算法. 算法的内层多模型由当前统计模型和恒速模型构成, 针对目标的速度方向角进行滤波, 将获得的角速度估计值作为外层的中心角速度; 外层多模型由转弯模型构成, 其角速度集合由中心角速度和对称角速度(交互输出的加速度与速度的比值)组成. 由于既准确估计了目标的角速度, 又设计了合理的角速度集合, 算法显著提高了转弯机动目标的跟踪精度. 仿真实验验证了算法的有效性. |
| 英文摘要 |
| A novel two-layer interactive multiple model (IMM) tracking algorithm for turn maneuver is proposed. It contains the inner layer and the outer layer. The inner layer is composed of current statistical model and constant velocity model. The central angular velocity for outer layer can be attained by filtering the heading angle of target. The outer counterpart is composed by constant turn models, in which the angular velocity set includes the central angular velocity and symmetric angular velocity. The latter is computed by the ratio of the target acceleration and velocity. Because of the reasonable design of the angular velocity set, the tracking precision for turn maneuver is improved significantly. Experiment demonstrates the efficiency of the proposed algorithm. |
