| 中文摘要: |
| 研究了单矢量传感器多重信号分类(SV MUSIC)算法对非相干源的分辨性能，推导了声源等功率情况下的信噪比分辨门限表达式。针对相干源的分辨问题，提出了一种基于空间平滑的二元矢量阵多重信号分类(DV MUSIC)算法。仿真实验表明，SV MUSIC算法对非相干源的分辨能力随着信噪比的增加而提高，在相应的判定准则下其结果与理论值基本吻合，而基于二元矢量传感器的DV MUSIC算法能够实现相干源的分辨，其分辨性能曲线一定程度上类似于SV MUSIC算法对非相干源的分辨性能曲线。 |
| 英文摘要: |
| The performance of the single vector sensor multiple signal classification (SV MUSIC) algorithm for resolving incoherent sources was researched, and the expression of SNR resolution threshold when sound sources are equal in power was deduced. And then for coherent sources, a dual vector sensor multiple signal classification (DV MUSIC) algorithm was presented based on the spatial smoothing method. It was shown by simulation that, the resolution performance of the SV MUSIC algorithm for incoherent sources was improved as the SNR increasing, which meets the theoretical value under specified criterion. Based on a dual vector sensor array, the DV MUSIC algorithm was used to distinguish coherent sources and its resolution performance curve was similar to that of the SV MUSIC algorithm for incoherent sources to a certain extent. |
