| 摘 要： | 文中研究了弹载传感器利用时差和方位信息进行无源定位时的无解和模糊问题,并利用MAPLE通过数学推导,从理论上证明了理想情况下弹载传感器利用方位和时差信息进行无源定位不存在无解问题。同时,文中还对定位模糊问题进行了分析,并通过仿真对模糊问题受测量精度、基线长度等因素影响的情况进行了研究,给出了目标跟踪精度图。

| Abstract: | The ambiguity and non-solution problem of TDOA and DOA location system on missile is studied in this paper.Through mathematical calculation using MAPLE this paper proves that the real root of this passive location system can always be obtained.In other words,that there is not non-solution problem in theory.Simulation is made,and the influence of baseline length and measurement error on ambiguity problem is also analyzed.The position RMS error of target is given. |
