| 摘 要： | 平均信噪比分辨门限是特征结构算法分辨性能的一种度量,本文给出了含有两信号源相关性的MUSIC算法的平均信噪比分辨门限表达式.模拟结果表明,当两信号源正相关时,MUSIC算法分辨性能会下降;当负相关时,在一定条件下,MUSIC算法分辨性能会提高.本文也讨论了当两信号源的功率差异、方向夹角、阵元数和采样的快拍数变化时,相关性对算法分辨性能的影响的变化规律.

| Abstract: | The mean SNR resolution threshold is a kind of measurement of resolution performance of the eigenstructure algorithms.The formula of the mean SNR resolution threshold of MUSIC algorithm which includes the correlation of two signal sources is deduced.Simulation results show that the positive correlation may reduce the resolution performance of MUSIC algorithm,and that under some condition the negative correlation may improve the resolution performance.The rule of the effect change of correlation on the resol... |
