摘要
本文以均匀圆阵模式空间内的二维ESPRIT算法为基础 ,推导出用实数特征分解代替复数特征分解的改进算法。改进算法运算量减少 ,且因其构造的信号子空间与阵列方向向量张成的空间更相近 ,所以DOA估计的性能有所提高。计算机模拟结果证明了以上结论。
An improved 2-D ESPRIT algorithm for DOA estimation with the Uniform Circular Arrays is developed in this paper. By using it, the estimators are more accurate while the computation is less complicated due to the real computation and the construction of the signal subspace via the pre knowledge of the array.
