【Abstract】 The application of Bartlett and Capon spatial spectra estimation methods is expanded to vector sensor array. Expressions of the spatial spectra based on acoustic vector sensor array are derived. Compared with the expressions based on traditional pressure sensor array, improvements are attained by using acoustic vector sensor array for directionofarrival(DOA) estimation. The numeric examples have proven the results.更多还原
