提出了基于2
q
阶累积量的非圆信号测向MUSIC(Multiple Signal Classification)算法(称为NC-2
q
-MUSIC)
作为2
q
-MUSIC算法利用非圆信息的一种扩展
在可测向信号数、分辨力和测角精度等方面的性能均优于2
q
-MUSIC算法.并且
q
越大
NC-2
q
-MUSIC算法的可测向信号数越大
分辨力越高
对模型误差也越不敏感.针对均布线阵(ULA:Uniform Linear Array)提出的NC-2
q
-MUSIC/ULA算法减小了计算量.仿真实验验证了NC-2
q
-MUSIC算法的优良性能.
The NC-2
q
-MUSIC(Multiple Signal Classification)algorithm
which is an extension of the 2
q
-MUSIC algorithm to noncircular(NC)applications
is proposed.The performance of NC-2
q
-MUSIC algorithm for noncircular signals is better than 2
q
-MUSIC algorithm due to the utilization of noncircular information of signals.The resolution and robustness to modeling errors of NC-2
q
-MUSIC algorithm become better with the increase of
q
.The computational complexity of the NC-2
q
-MUSIC algorithm is analyzed and the NC-2
q
-MUSIC algorithm for uniform linear array(ULA)
needs much less computation is also proposed.Simulation results show the better performance of NC-2
q
-MUSIC algorithm over 2
q
-MUSIC and validate other conclusions about NC-2
q
-MUSIC.
