摘要
卫星导航生成式欺骗干扰通过发播伪造的导航信号,诱使目标区域内接收机捕获、跟踪该欺骗信号,从而使接收机解算出错误的位置、时间信息。欺骗干扰信号高度仿真卫星信号,功率远低于噪声,目前抗干扰方法均无法有效识别、抑制,是一种有效的干扰方式。研究了卫星导航生成式欺骗所需的关键技术,介绍了较为成熟的反馈式欺骗干扰源设计方案,讨论了欺骗干扰有效实施的方法。
GNSS spooler broadcast forgery navigation signals to make victim receivers acquire, tracking and obtain wrong position and timing solutions. Spoofing signal can not be detected and removed by exciting anti-jamming algorithms for the high similarity with auth signal and low power. The key technologies of generated spoofing are studied, a reeeiver-spoofer GNSS spoofing structure is introduced, then the principles of a successfully spoofing jamming are discussed.
