| 摘 要： | 由天线阵对被测信号的响应矩阵的特征值,可得到对应于信号和噪声的特征向量,以此扩展成信号子空间和噪声子空间。利用信号子空间与噪声子空间的正交关系,即可求得信号方位角的估计值。这种空间谱估计测向的MUSIC算法,用于圆形天线阵对非相干信号进行测向,可以克服一般干涉仪测向体制中测向模糊和测向盲区的问题。 |

| Abstract: | The responses of antenna array to the signals which to be measured are composed to be a matrix.From its eigenvalue,the eigenvectors corresponding to the signals and noise can be obtained.And the sub-space of the signals and noise can be expanded through them.With the quadrature between the sub-space of the signals and noise,the estimate value to the angle of arrival(AOA) of the signals was obtained.MUSIC algorithm is a typical method of the space spectrum estimation of direction,which can be used in the round array of antennas to find directions of non-correlative signals,will overcome the questions in the common system of director finding by interferometer,which are the illegibility and the blind-section. |
