文摘

•: An alternative formulation of the time-domain beamforming is proposed.
•: Generalized Cross-Correlation (GCC) is used instead of Cross-Correlation operator.
•: A spatial weighting function is introduced to sharpen the imaging result.
•: Numerical and experimental validation is proposed for multiple sources localization.
