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.但目前对单天线转发式欺骗干扰区域映射特性研究较少.本文对单天线直接转发式欺骗干扰的区域映射特性进行研究,分别从公式推导、仿真数值计算和实验验证等方面对其进行综合研究.先对单天线的转发式欺骗干扰模型进行数学公式推导 ,从理论上证明其区域向单点映射的物理特性 ,通过对欺骗区域内多个接收机定位方程的解算 ,得到转发式欺骗干扰区域映射的特性,即欺骗干扰覆盖区域内不同接收点的位置解算结果仅与欺骗信号有关 ,每个点定位的区别仅仅是钟差偏移量的不同.通过M atlab数值计算对公式推导的结论进行验证.再进一步进行实测验证 ,试验结果充分验证了本文的结论 ,为后续欺骗干扰的检测算法设计提供了理论依据.
