摘要: 该文研究直接序列扩频通信系统天线阵列标校问题。提出了一种基于PARAFAC与阵列旋转的阵列标校方法。该方法利用直接序列扩频通信信号特点以及平行因子的分析方法对阵列通道参数进行估计，并结合天线阵列的旋转技术得到一种阵列有源标校方法。该方法无需知道标校源信号的波达角，就可对阵列进行标校，给实际应用带来方便。仿真结果表明该方法可行、有效。Abstract: The array calibration for spreading communication system is discussed in this paper. Based on both PARAFAC and array rotation, an array calibration approach is proposed. This calibration approach is employing auxiliary spreading code signal, PARAFAC analysis and array rotation. Array calibration can be performed without the DOA knowledge of auxiliary signal, which is convenient in practice. Simulation result shows that the calibration approach is feasible and efficient.
