摘　　要：论述了利用空间谱估计进行超分辨测向的基本理论 ,分析并给出了适用于任意形状超分辨测向天线阵的通用测向算法 ,并采用差值算法对被测信号的频谱范围进行了扩展 ,利用Music算法及Matlab语言编制了相应的软件 ,同时对两种常用测向天线阵的性能进行了计算机仿真实验研究 ,并给出了一些具体的实验结果。此结果可作为超分辨测向工程实现的技术参考。This paper first discussed the basic theory of super-resolution direction estimation which is disposed by Spectrum estimation of space. Then it analyzed and presented the common arithmetic about arbitrary antenna array in super-resolution direction estimation and expanded spectrum of signal through using difference arithmetic. At last it authorized corresponding software by Music arithmetic and Matlab language. At the same time the performance of super-resolution direction estimation of two common used antenna arrays has been put into emulation. The outcome in the paper has been presented through the emulation experiment and it can be used as technological and theoretical base in super-resolution direction estimation engineering.
