Abstract
随着全球导航卫星系统 (global navigation satellite system, GNSS) 应用的日益广泛和欺骗攻击威胁的日益加剧, 针对商用接收机开展反欺骗研究是十分必要和迫切的. 本文提出了一种面向商用接收机的 GNSS 欺骗干扰源测向方法, 该方法利用水平面内运动接收机提供的多普勒观测量和钟漂解算信息构造双差观测量, 计算提取了由接收机运动产生的多普勒信息, 并利用该信息实现欺骗干扰源测向. 本文给出了欺骗源方位角和仰角测量的最大似然 (most likelyhood, ML) 估计方法, 推导了克拉美罗下界 (Cramer-Rao lower bound, CRLB) ，分析了影响角度估计性能的因素, 并通过外场试验验证了所提方法的有效性.
