摘要：
A beamforming device, an ultrasonic imaging device, and a beamforming method, which allow a simple spatial smoothing operation, are disclosed. A beamforming device according to an embodiment of the present invention comprises: a spatial smoothing unit for transforming a received signal into another space, using a transformation function configured by low frequency components, calculating a transformed signal by a spatial smoothing operation using a transformation function in a transformation space, and estimating an averaged spatial covariance matrix； a weighted value operation unit for operating a weighted value of the transformed signal from the averaged spatial covariance matrix which has been estimated by the spatial smoothing operation； and a synthesis unit for generating a beam signal, using the transformed signal and the weighted value of the transformed signal.
