一种基于非平稳性分析的虚假定位点识别方法
A novel method for false location identification based on nonstationary verification

摘要: 该文分析了运动无源定位系统中虚假定位点的发散特性,得出虚假定位点是具有趋向性均值的非平稳过程这一结论。在此基础上提出一种基于非平稳性检验的虚假定位点逆序检验方法。在较大测量误差条件下,这一方法能够比传统方法更加可靠和迅速地识别出虚假的定位点,而且具有较好的操作性。仿真证明了文章的观点。

Abstract: In this paper, the divergence characterization of false location in moving passive location system is analysised. Conclusion that false location is kind of nonstationary random of mean value with trend is presented. A novel method for false location identification based on nonstationary verification is brought forward. Simulations prove the algorithm valid even in the high noisy environment. -
