| 摘 要： | 提出一种实用的前后向空间平滑(RFBS)算法,从理论上定量分析了统计意义下子阵数目与前后向空间平滑算法解相关性能的关系.理论分析表明,采用该算法后,可明显降低相关信号源的相关系数,且该方法不破坏非相关信号源的独立性.计算机仿真了在总阵元一定的情况下,子阵数目与相干信号源数目分辨概率在不同信噪比下的相互关系,并验证了算法的有效性. |
| 关 键 词： | 相关信号源 RFBS算法 相关系数 |

| Abstract: | A practical realization of forward-backward spatial smoothing algorithm is proposed.The relationship between the number of sub-arrays and the de-correlating performance of spatial smoothing algorithm is analyzed quantitatively in the case of stat sense.Academic analysis indicates that the correlation coefficient is reduced and the independence among uncorrelated signal sources is reserved after adoption of the algorithm.At the end,simulated results about the mutual relation between the number of sub-arrays ... |
