Abstract：This paper defines the mean SNR’s resolving threshold which can measure the resolving performance of MUSIC algorithm, and deduces the expression of the resolving threshold. The data simulation show that the power difference of the two signal sources can reduce the resolving ability of MUSIC algorithm, that the relative effect of the power difference on the resolving performance of MUSIC algorithm has nothing with other parameters under certain condition. This paper also discusses the effect of the power difference on the number of array element, the number of snap shot and the absolute subtract of the two signal sources’ orientation parameter.
