The Analysis of Multi-Node Deceptive Interference Detection Algorithm Based on Location Coordinate
-
摘要: 欺骗干扰由于其功率小、隐蔽性强等优点,逐渐成为干扰卫星导航信号的重要手段。本文使用基于定位位置的多节点欺骗干扰检测中常用的模型,通过NeymanPearson方法推导出了基于定位坐标的多节点欺骗干扰检测算法,该算法可以得到不同欺骗条件下的观测量阈值和检测概率的表达式,这为基于多节点实地检测欺骗提供理论依据。Abstract: Because of its small power and high concealment, deception spoofing is becoming an important means to interfere with satellite navigation signals.By using the multi-node deception spoofing detection based on positioning location that is commonly used in model and through the Neyman-pearson method, this article deduced a multi-node deception spoofing detection algorithm based on location coordinates. This algorithm can obtain the expressions of threshold measurements and detection probability in different deception conditions, which can provide the theory basis for multi-node field detecting deception.
