摘要
研究利用导向最小方差(STMV)法实现了宽带相干信号的一维和二维高分辨DOA估计。与传统的最小方差无畸变响应(MVDR)法相比,STMV法更适于处理宽带信号。由于利用了导向协方差矩阵的时空统计特性,该方法比MVDR具有更高的空间分辨力和更好的稳健性。
The STMV（STeered Minimum Variance） is investigated to realize high resolution 1-D and 2-D DOA estimation for broadband correlated signal. Compared with the conventional MVDR（Minimum Variance Distortionless Response） method, the STMV is much proper in broadband signal processing. Furthermore, it has greater resolving power and stability.
