代码说明:

  在现代谱估计中,用自相关的无偏估计代替周期图中自相关函数的有偏估计,可能导致出现负的谱估计值,因此采用BT谱估计器的方法(In the modern spectral estimation, the use of self-related unbiased estimate the figure to replace the cycle of auto-correlation function biased estimate may lead to a negative estimated value of the spectrum, so the use of BT s method of spectral estimation)

    MUSIC算法[1]是一种基于矩阵特征空间分解的方法。从几何角度讲,信号处理的观测空间可以分解为信号子空间和噪声子空间,显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成,噪声子空间则由协方差矩阵中所有最小特征值(噪声方差)对应的特征向量组成。(MUSIC algorithm [1] is a feature space based on matrix decomposition method. From the geometric point of view, the signal processing can be decomposed observation space the signal subspace and the noise subspace, it is clear that the two spaces are orthogonal. Signal Subspace data received by the array covariance matrix and eigenvectors corresponding to the signal component, the noise subspace from the covariance matrix of all the smallest eigenvalue (noise variance) eigenvector components.)
