A DBF method of localizing accuracy improvement and speech enhancement based on a new microphone arrays

There is a widely application in radar and mobile communication of target localization field recent years about DBF, But the contradiction between precision of target localization and localization out of focus haven't been solved preferably. This article put forward a new linear microphone arrays which own two frameworks that can change space between arrays so that can resolve this contradiction. This method make beam-riding of mainlobe point to interested targets more precisely, enhance quality of receive signal and cut down reverberation in some degree. The result proves validity of this new array structure.
