| 摘 要： | 本文介绍了用修正ＭＵＳＩＣ算法提高相关信号源ＤＯＡ估计性能的方法。理论分析表明，采用该方法后，可将相关信号源的相关系数平均降低为原来的６３％，因而可改善ＭＵＳＩＣ算法对相关信号源的ＤＯＡ估计性能。且该方法不影响对非相关信号源ＤＯＡ的估计，计算量也无明显增加。计算机仿真实验结果验证了上述理论分析的正确性。

| Abstract: | In this paper,the method of improving DOA estimation performance for correlated signals by using modified MUSIC algorithm is concerned It has been demonstrated that the average correlation coefficient between correlated signal sources will theoretically fall to 63 percent in post processing,so that it is possible to improve the DOA estimation accuracy for correlated signals In addition,the DOA estimation of uncorrelated signals will not go bad,as well as the computational complexity will not increase obviously Finally,some simulation results verifying the theoretical analysis are given in the paper |
