    经典的MUSIC算法可对非相干信号实现很好地估计,在相干信源的情况下经典的MUSIC算法失效,无法准确估计出信源波达方位角度。引入空间平滑技术来对相干信号进行预处理,以减弱或消除信号之间的相干性,改进后的MUSIC算法能对相干信号的DOA 实现精确估计。(The classical MUSIC algorithm can achieve a good non-coherent signal is estimated that in the case of coherent sources the classic MUSIC algorithm is disabled, can not accurately estimate the source azimuth angle of arrival. Spatial smoothing technique to the introduction of coherent signals pretreatment to weaken or eliminate the coherence between the signals, the modified MUSIC algorithm for DOA of coherent signals to achieve precise estimates.)

  • dc
    DC Defect Correction Method. X = DC(A,B) attempts to solve the system of linear equations A*X = B for X. The N-by-N coefficient matrix A must be square and the right hand side column vector B must have length This uses the defect correction method until default convergence criteria or MAXIT iterations is reached.
