摘要
针对异类传感器的非线性机动目标跟踪中,由于采样信息差异、目标强机动等原因造成的跟踪性能低或失效等问题,提出UKF_IMM跟踪算法并进行了仿真计算。该方法直接面向极坐标量测信息,计算量小,且有较强的鲁棒性。仿真结果表明:该跟踪方法能获得较高的目标跟踪精度,系统反应时间短,目标跟踪稳定、连续,有重要的工程参考价值。
Based on the problem of low tracking capability because of different information and maneuver in nonlinear maneuvering target tracking with multi_information, an algorithm based on UKF_IMM is proposed, which is easy and maneuvering. Simulation result shows that the algorithm can acquire better precision of target tracking, and the working time of the system is shorten, target tracking is steady and consecutive, which satisfies the require of tracking capability and offerse reference for the project.
