Abstract
Large array extent is usually required in order to adequately enhance the resolution of a beamformer and to improve its beam pattern. Due to physical constraints this requirement may not be met. This paper presents the results of a 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 beamformer can be improved. Examples for various situations are provided.
