基于波束空间MUSIC的MIMO雷达波达方向估计

摘要

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.%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.
