There are mainly two type of algorithms used for spatial spectrum estimation : one is those based on bayesian maximum likelihood method, like the ml ( maximum likelihood ) algorithm, maximum entropy method and etc., the others are based on the spatial decomposition or projection of correlation matrix, this kind of algorithm include vector characterization method, music ( multiple signal classification ) algorithm, projection matrix method, etc. music is a classical spatial spectrum estimation algorithm that has a super high resolution and is widely used today, however, it cannot estimate doa of signals that are correlated
空間譜估計的演算法大致分兩大類:一是基於極大似然估計和最大后驗概率估計統計理論的演算法,包括:極大似然估計法( ml ) 、最大熵法等;另一類是基於對協方差矩陣進行子空間分解或投影的演算法,包括:矢量特徵法、多重信號分類法( music ) 、投影矩陣法等。其中, music法是一種經典的空間譜估計主流演算法,具有超強的分辨性能,但它無法實現對相干信號進行測向分辨。
