针对杂波环境下多变采样率传感器多目标跟踪问题,考虑到二次雷达(SSR)具有辨别敌我方目标和更精确的高度探测能力,本文提出了一种带SSR修正的异步多传感器系统的无味JPDA跟踪算法.该算法首先通过测量值映射的异步数据处理方法对多传感器数据进行点迹的合成,然后通过二次雷达对敌方目标的高度信息进行自适应修正,最后用无味JPDA算法对按序到来的异步采样量测进行顺序滤波融合.通过蒙特卡洛仿真,表明该算法在提高目标跟踪精度和正确关联概率上是有效的.

Aiming at the problem of variable sampling rate sensor multi-target tracking in clutter,considering the ability that Secondary Surveillance Radar(SSR) can identify enemy or friend target and enhance the accuracy of tracking enemy target,a SSR modified unscented Joint Probabilistic Data Association(JPDA) tracking algorithm is proposed for multi-sensor asynchronous system.Firstly,by using asynchronous data dealing way of mapping measurements,point track of the multi-sensor measurements is composed.Secondly,SSR is used to modify the height information of the enemy target adaptively.Finally,by using the unscented JPDA algorithm,the sequential filtering fusion of asynchronous sampling measurements can be realized.The validity of this algorithm on the improvement of target tracking accuracy and correct associate probability is illustrated through Monte-Carlo simulations.
