1. A method for digital beamforming comprising:
(a) receiving, by a digital beamformer from a first principal polarization frequency converter, a first modulated signal associated with a first intermediate frequency;
(b) converting, by the digital beamformer, the first modulated signal to a digital data format to provide first digital data;
(c) generating, by the digital beamformer, a first plurality of channels of digital data by decimating the first digital data using a first polyphase channelizer and filtering using a first plurality of cascaded halfband filters;
(d) selecting, by the digital beamformer, a first channel of the first plurality of channels;
(e) applying, by the digital beamformer, a first weighting factor to the first digital data associated with the first channel to generate a first intermediate partial beamformed data stream;
(f) combining, by the digital beamformer, the first intermediate partial beamformed data stream with a plurality of other intermediate partial beamformed data streams to generate a first partial beamformed data stream;
(g) applying, by the digital beamformer, a first oscillating signal to the first partial beamformed data stream to generate a first oscillating partial beamformed data stream;
(h) applying, by the digital beamformer, a first three-stage halfband filter to the first oscillating partial beamformed data stream to generate a first filtered partial beamformed data stream;
(i) applying, by the digital beamformer, a first time delay to the first filtered partial beamformed data stream to generate a first partial beam, wherein the first partial beam is of a first beam; and
(j) transmitting, from the digital beamformer, via a data transport bus to a digital software system interface, the first partial beam of the first beam, which is transmitted via the data transport bus along with a first set of a plurality of other partial beams of the first beam.
