摘要 |
A beamformer for forming a reception beam using a multichannel signal reflected from a subject is provided. The beamformer includes a signal generator that may generate a plurality of signals to which different apodization functions are applied, with respect to the multichannel signal, an estimator that may estimate a signal predominant component and a noise predominant component from the plurality of signals, a weight calculator that may calculate a weight to be applied to the signal predominant component according to each of channels, using the estimated signal predominant component and the estimated noise predominant component, and a weight applier that may apply the calculated weight to the estimated signal predominant component. |
