| 摘 要： | 阐述了蜂窝网系统中单台定位设备TSOA/TDOA被动式新型混合定位技术的原理.利用TSOA/TDOA混合定位的数学模型建立系统观测方程,采用受随机加速影响的匀速运动状态模型,描述了移动台的位移和速度.在此基础上推导了基于平方根无迹卡尔曼滤波的跟踪算法,并通过仿真实现了对移动台位置和速度的同时跟踪.仿真结果表明,与扩展卡尔曼滤波及无迹卡尔曼滤波算法相比,平方根无迹卡尔曼滤波算法的跟踪性能更优.

| Abstract: | According to the single location equipment application in cellular networks,the principle of a novel passive location technology is firstly presented in detail based on the time sum of arrival and the time difference of arrival(TSOA/TDOA).Then the equation of observation is built by the mathematical model of the TSOA/TDOA location system.And the speed and shift of the mobile are described with the uniform motion state model which is affected by the random acceleration.Finally,the locating and tracking algorithm is put forward and derived based on square-root unscented Kalman filter(SRUKF).And the mobile position and speed are estimated at the same time.Simulation result shows that the proposed algorithm has superior performance to the extended Kalman filter(EKF) algorithm and the unscented Kalman filter(UKF) tracking algorithm. |
