【摘要】 传统基于均匀直线阵多通道的空间谱估计定位系统,体积庞大,设备昂贵。本文通过使用虚拟天线阵列代替均匀直线阵,简化了定位系统。本文先简单介绍了空间谱估计法,然后提出虚拟天线阵列,并通过相位矫正使得虚拟天线阵列等效于均匀直线阵,最后给出了实验结果及结论。更多还原

【Abstract】 Traditional spatial spectrum estimation positioning system based on uniform linear array multi-channel positioning system is bulky and expensive.For this kind of situation, this paper proposes using virtual antenna array instead of uniform linear array, to simplify the method of positioning system. First of all the spatial spectrum estimation method was introduced, and virtual antenna array was put forward, then virtual antenna array is equivalent to uniform linear array through phase correction,at last,the feasibility of this method is proved through field experiments.更多还原
