摘要: 通过研究多个导向矢量之间的线性无关性讨论电磁矢量传感器及其阵列累量域观测的唯一性问题。导出了累量域电磁矢量传感器及其阵列线性无关虚拟导向矢量个数的上界和下界。这些结论对确定电磁矢量传感器及其阵列累量域可分辨非高斯信号源个数具有一定的参考价值。给出的仿真实验结果验证了文中的分析和推导。Abstract: The number of linear independent steering vectors effected by an ElectroMagnetic (EM) Vector Sensor (VS) and an EMVS array in cumulant domain is investigated in this paper. The upper bound and the lower bound for the number of linear independent steering vectors are both derived. The conclusions are useful for determining the number of non-Gaussian narrow-band signals whose DOAs can be uniquely identified by one EMVS or an array comprising multiple EMVSs. Simulation results validate the present derivations.
