| 摘 要： | 在冲击噪声背景和相干信源下，基于高斯白噪声的DOA估计算法完全失效，为了解决该问题，本文提出了一种改进的TLS—ESPRIT算法。本算法的原理是结合分数低阶矩阵知识，将空间平滑理论应用于TLS—ESPRIT算法之中。本文算法无需进行空间谱搜索，因而大大地减少了计算量。计算机仿真实验证明，在冲击噪声背景和多径干扰下，新算...

| Abstract: | Under the impact of noise background and disturbed source,the DOA estimation algorithm based on gaussian white noise is ineffective.In order to solve the problem,this paper proposes an improved TLS-ESPRIT algorithm.The principle of this algorithm is to apply spatial smooth theory to the TLS-ESPRIT algorithm combining with fractional lower order matrix knowledge.This algorithm does not need to search space spectrum,which greatly reduces the computation time.The simulation experiments of computer prove that u... |
