基于模式切换的有源无源一体化跟踪算法研究

针对传统目标跟踪算法缺乏灵活性，不能满足复杂环境下目标连续跟踪的缺点，探讨了网络雷达不同工作模式下，接收站获取目标运动状态参数不同集合对目标跟踪精度的影响，提出了基于模式切换的有源无源一体化跟踪算法，该算法可根据接收站的不同需求灵活选择有源无源等不同的定位跟踪方式。采用UKF算法对不同模式切换下的目标跟踪精度进行分析，仿真结果表明，该算法能够有效利用前一阶段的滤波跟踪结果，可在复杂的环境下保持对目标的连续跟踪。

Research on integrated target tracking algorithm based on switching modes

Aiming at the defect of the traditional target tracking algorithm that can not maintain contiguous target tracking in the complex circumstance. This paper discusses the target tracking precision influence of the different parameters muster gained by the receiver in various working modes of network radar. And then a new integrated target tracking algorithm based on switching modes is put forward. This algorithm can select the different target tracking modes neatly according to various requirements of the receiver. This paper analyses target tracking precision of the integrated target tracking algorithm by UKF algorithm. And the simulation indicates this algorithm can utilize the previous tracking result, and can obtain a continuous tracking status under complex circumstance.
