    Abstract

    Large array extent is usually required in order to adequately enhance the resolution of a beamformer and to improve its beam pat-tern. Due to physical constraints this requirement may not be met. This paper presents the results of an analytical and experimental study in the use of a signal extrapolation method to enhance the beamformer resolution for small array extent. A real-time implementation scheme is proposed. It is shown that the beam pattern and the resolution of the beamforrner can be improved. Examples for various situations are provided.
