MUSIC算法多值模糊问题研究

Study of MUSIC algorithm about blur of multiple value

针对阵列测向 ,概括论述了空间谱估计算法中最为经典的算法———MUSIC算法的基本思想和方法 ,从理论上推导出天线距离大于信号源载频波长的一半时产生多值模糊的原因 ,给出了多值之间的数学关系公式 ,并基于MAT LAB程序进行了计算机仿真 ,仿真结果与理论分析达到了很好的吻合 。

To direction finding on antenna array, this paper first discussed classical algorithm——MUSIC algorithm in space spectrum estimate. Then it deduce the causation of coming into being blur of multiple value in theory when the distance of antenna is longer than the wavelength of carrier frequency about signal. The outcome in the paper has been presented about the formula on maths between multiple value. The algorithm has been put into emulation on MATLAB programme and it has identical results with the theory. To the issue of blur of multiple value, it brings forward the assume about the solving project.
