| 摘 要： | 针对相干信号源超分辨空间谱估计中存在的问题，本文提出了空间平滑差分方法。利用常规超分辨方法估计不相关源和相关源的空间谱，利用空间平滑差分方法估计相关源和相干源的空间谱，这样可以重复利用接收阵列输出数据，兼顾不相关信号源和相干信号源的空间谱估计，因而可以估计更多的信号源。

| Abstract: | Spatial Smoothing Differencing Technique is presented for estimation of spatial spectrum of coherent sources with a uniform linear array. A common algorithm can estimate DOA of uncorrelated and correlated sources. While the spatial smoothing differencing algorithm can estimate DOA of correlated and coherent sources. In this way the output data of the array are used repeatedly, and therefore more sources can be estimated with fewer sensors. |
