Abstract:
1. A time multiplexed device for beamforming, the device comprising: an echo data write/read unit for buffering each echo data that are converted from analog to digital in each channel, and reading the written echo data therefrom by means of time multiplexing based on the requirement of a beam data processing; a multi-beam processing unit for interpolating and apodization processing upon the beam data read from the echo data write/read unit in each channel, by means of time multiplexing, wherein the multi-beam processing unit comprises an interpolation processing module and an apodization module; a channel data summing unit for summing, by means of time multiplexing, the data processed by the multi-beam processing unit, to lead to the final beam data; and a parameter distributing and synchronizing unit for distributing and synchronizing respective receive parameters to the echo data write/read unit and the multi-beam processing unit through a parameter load bus for each of the beams in the channel, wherein the interpolation processing module is configured to receive respective receive parameters from the parameter load bus, time multiplexed delayed beam data, and interpolation coefficient selection parameters, and to generate interpolated beam data, and wherein the apodization module is configured to receive respective receive parameters from the parameter load bus and the interpolated beam data and to generate apodized beam data.
