针对这些问题,在传统的四阶累积量多重信号分类(multiple signal classification,MUSIC)算法基础上提出了一种改进的算法。该算法根据四阶累积量矩阵构成的规律,去除了原四阶累积量矩阵的数据冗余, 有效地减小了运算时间,为其实际应用提供了必要条件。计算机仿真和实测数据仿真的结果表明,本改进算法可以快速地实现虚拟阵列扩展,同时对有色高斯噪声也 有一定的抑制-Aiming at these problems, an improved algorithm based on signal classification (MUSIC) algorithm is proposed, which is based on the traditional four order multiple. According to the rule of the four order accumulation matrix, the algorithm removes the data redundancy of the original four order cumulative quantity matrix, effectively reduces the computation time, and provides the necessary conditions for its practical application. The simulation results show that the improved algorithm can quickly realize the virtual array expansion, and it can also restrain the colored Gauss noise.
