摘　　要：利用移动台定位是未来移动通信的方向,研究者们提出了不少的定位方法。其中较多方法适用于移动台处于静止状态下的定位,但当移动台处于移动状态时却存在较大的误差。因此,该文提出了一种基于马尔科夫链配合相关检测距离门的定位跟踪算法,并推导了定位跟踪算法实现方法。理论分析和仿真结果表明,该定位跟踪算法不仅能够实现移动台处于移动状态下和静止状态下的定位,而且提高了其定位精度。In the future, using mobile station to locate is the trend of the mobile communication. There are many scholars research in this technology and hold up a great amount of location methods. But many of methods only are fit for location of the mobile station which is in the quiescent state. And when the mobile station is in the dislocation state, these methods would occur fair-sized error. This paper holds up a location track arithmetic which bases on Markov chain cooperating to correlation detection range gate and derives the implementation method of the location track arithmetic. Theoretical analysis and simulation result shows that this location track arithmetic could implement location of the mobile station not only in the dislocation state but also in the quiescent state and improve location accuracy.
