| 摘 要： | 本文提出了一种基于最小冗余线阵的谱相关共轭循环ＭＵＳＩＣ 算法。该算法构造了最小冗余线阵的伪数据矩阵并由此进行ＤＯＡ 估计。当采用Ｍ 阵元最小冗余线阵时，该算法的等效阵列孔径为２Ｎ－ １（Ｎ＞ Ｍ） 。理论和计算机仿真实验均表明：与基于均匀线阵的共轭循环ＭＵＳＩＣ 算法相比，该算法具有良好的ＤＯＡ 估计性能，扩展了阵列孔径，抗噪能力强，分辨率高，能用较少的阵元估计更多的信号源方向

| Abstract: | A novel spectral correlation conjugate cyclic MUSIC algorithm based on minimum redundancy linear array (MRLA) is proposed in this paper.The algortihm constructs a pseudo data matrix for MRLA,by which the DOAs of narrow band signals are estimated.It is proved herein that the effective array aperture is 2N-1(N>M) when M-element MRLA is adopted.The theoretical analysis and computer simulation show that,compared with traditional conjugate cyclic MUSIC algorithm based on common linear array,the proposed method has better performance on the DOA estimation,array aperture extension,noise suppression,angular resolution and is capable of estimating more DOA with less elements. |
