| 摘 要： | 在进行波达方向估计时，阵元空间MUSIC方法的计算量通常都比较大。为了解决此问题，采用了波束空间MUSIC的方法，它的计算量较阵元空间MUSIC方法有所下降，将它运用于多输入多输出雷达波达方向的估计问题。计算机仿真实验表明，虽然协方差矩阵特征分解的计算量下降了，但是波束空间MUSIC的性能依然良好。

| Abstract: | The array-space MUSIC requires large calculated amount usually during DOA estimation.In order to resolve this problem,the algorithm based on beam-space MUSIC is adopted.The calculated amount of this algorithm is lower than array-space MUSIC and is used in MIMO radar DOA estimation.Simulation results show that the performance of beam-space MUSIC is good all the same though the calculated amount of eigen-decomposition of covariance matrix is reduced. |
