摘要
针对杂波区内目标跟踪数据关联错误率较高的问题,利用检测前跟踪技术,将点迹幅度的积累和航向变化的稳定性参数,作为多假设跟踪(MHT)算法中假设生成及假设删除的对象。同时,对MHT的核心算法进行优化,为MHT的工程应用提出一种解决方法。通过M atlab数据分析仿真和实际工程验证,该方法可提高目标在杂波环境下的跟踪稳定性。
Aimed at the high error rate of target tracking data relevance in the clutter region, the track-before-detect technology is used. The technology can use accumulation parameters of the point trace amplitude and the stability of the trace change as targets for hypothesis generation and hypothesis deletion in multiple hypothesis tracking （MHT） algorithm. The core algorithm of MHT is optimized and a method for MHT engineering applications is proposed. The Matlab data analysis simulation and the actual engineering verification show that the method can improve tar- get tracking stability in the clutter region.
