摘要
针对卫星导航欺骗干扰信号的识别与智能对抗问题,本文将阵列信号处理中的空间谱估计技术与自适应阵列处理技术相结合,提出了一种基于旋转不变子空间(estimation of signal parameters via rotation invariant tech⁃nique,ESPRIT)算法与基于生成信号采样矩阵求逆(generated-signal sample matrix inversion,GS-SMI)算法的欺骗干扰信号识别、欺骗干扰方向自适应零陷形成的方法。通过仿真验证了所提出的方法对抑制卫星导航欺骗干扰影响的有效性,为进一步将阵列天线应用于构造的卫星导航欺骗干扰环境提供了理论支撑。
Aiming at global navigation satellite system(GNSS)spoofing signal recognition and intelligent anti-spoofing,this paper proposes a method of GNSS spoofing signal identification,spoofing signals orienting and adaptive nulling,based on estimation of signal parameters via rotation invariant technique(ESPRIT)algorithm and generated-signal sample matrix inversion(GS-SMI),combining the spatial spectrum estimation technology and adaptive array processing technology in array signal processing.The results of the simulation indicate that the proposed method is effective to restrain the influence of the GNSS spoofing attack.It provides theoretical support for further application of array antenna in GNSS spoofing environment.
