关 键 词：Array signal processing direction-of-arrival (DOA) estimation minimum variance (MV) nonuniform noise 

摘      要：The minimum variance （MV） approach is prevalent and useful in estimating the direction-of-arrival （DOA） of a broadband source using an array,and it has been well studied in the case of uniform sensor *** this paper,it is evaluated in another case of nonuniform white *** show that,compared to the temporal maximum-likelihood （ML） estimator,the MV estimator can give optimal performance while avoids the estimation of the nonuniform noise variances.
