| 摘 要： | 研究了三星测时差无源定位系统对地面机动辐射源定位与跟踪的滤波算法问题.将IMM滤波器应用到三星时差定位系统中,采用三模型组合的IMM滤波算法,首先通过时差测量参数计算出粗略的定位结果,接下来采用IMM滤波算法逐步估计出机动辐射源的速度和加速度,并修正初始的定位结果,提高定位精度.仿真结果表明,基于IMM滤波器的三星时差定位系统具有较快的收敛时间、较高的跟踪精度和适中的计算复杂度,能够对不同强度的机动目标进行定位与跟踪,很好地解决了三星时差定位系统对地面机动辐射源定位跟踪的算法问题.

| Abstract: | Based on the three satellites passive location system,the passive locating and tracking algorithm is studied in this paper.The IMM algorithm is applied to the three satellites location system.Based on three integrated models,firstly the location result is figured out with TDOA measurements,then the IMM is used to estimate the velocity and acceleration of maneuvering targets gradually,and the location perfomance is improved.The simulation indicates that the algorithm has short convergence time,high tracking ... |
