一种改进的信号特征矢量法

Improvement on Signal Eigenvector Method

相干信号源的波达方向估计仍是超分辨阵列信号处理中尚未彻底解决好的一个难题。为了更好地解决它，本文提出了一种改进的信号特征矢量法。该方法同信号特征矢量法相比，不仅可以估计更多的相干信号源，而且估计质量也有明显提高。

Direction of arrival(DOA) estimation of coherent sources is still a key problem in high reolution array signal processing. In order to further study it, an improved technique of the signal eigenvector method is presented. The technique can estimate more sources than the signal eigenvector method. Its estimating quality has been improved greatly.
