摘要: 該文分析了運(yùn)動(dòng)無(wú)源定位系統(tǒng)中虛假定位點(diǎn)的發(fā)散特性,得出虛假定位點(diǎn)是具有趨向性均值的非平穩(wěn)過(guò)程這一結(jié)論。在此基礎(chǔ)上提出一種基于非平穩(wěn)性檢驗(yàn)的虛假定位點(diǎn)逆序檢驗(yàn)方法。在較大測(cè)量誤差條件下,這一方法能夠比傳統(tǒng)方法更加可靠和迅速地識(shí)別出虛假的定位點(diǎn),而且具有較好的操作性。仿真證明了文章的觀點(diǎn)。

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. -
