信息融合在多目标跟踪中的应用研究

On Study of the Application of Message Fusion in Multiple－Target Tracking

本文着重研究了利用信息融合技术解决多目标跟踪中混批问题的方法．讨论以实际双基地系统的测量数据为依据，首先介绍了弱于扰条件下双基地系统对多目标跟踪时采用的互联算法；指出仅以目标动态参数互联容易发生混批现象，进而提出了融合目标状态、多卜勒频率（Ｆｄｓ）和雷达反射面积（ＲＣＳ）等信息的互联方法．从一百次统计结果看，采用信息融合技术之后，混批频率大为下降．

The paper emphatically studies the way for solving the problem of batch numberconfusion in multiple targets tracking by using message fusion technique. The discussion is on thebasis of measurement data of practical bistatic systems. At first the paper introduces association algorithms used in multiple targets tracking of bistatic systems under weak countermeasure condition and points out that batch number confusion easily happens if the dynamic parameters are theonly ones used for association process. And then it gives several association methods which fusemessage of target state, Doppler frequency(Fds ) and radar cross - section(RCS). From one hundredstatistical results it is clear that confusion frequency drops greatly when using message fusion techniques.
