摘要 本文介绍了将接收数据共轭重排的再利用，构造相关矩阵的修正ＥＳＰＲＩＴ算法。理论分析和仿真实验表明，该算法同经典的ＥＳＰＲＩＴ算法相比，在快拍次数有限时，可明显改善信号ＤＯＡ估计的性能，且其计算量二者基本相当。 This paper gives a modified ESPRIT algorithm that is based on the correlation matrix constructed by reusing the conjugate data being rearranged. Through theoretical analysis and simulation test, it has been indicated that by comparison with the typical ESPRIT algorithm, this modified ESPRIT algorithm can improve the performances of the signal DOA estimation obviously when the snapshot number is limited. Meanwhile, its computational complexity is about equal to that of the typical ESPRIT algorithm.
