Abstract
A method generates a dynamic tracking beam from an N-element receiving phased array antenna with a digital-beam-forming (DBF) network, N being an integer greater than 100, by performing digital beam forming to capture a desired signal from a moving source via the N-element phased array, including digitally multiplying received signals in the N-elements by a tracking beam beam weight vector (BWV) for the tracking beam, wherein the tracking beam BMV comprises N I/Q components; reading M pre-stored spot beam BWVs for M contiguous spot beams from a memory; determining a new tracking beam BWV for the tracking beam in a next update, wherein the new tracking beam BWV is a weighted sum of the M pre-stored spot beam BWVs of the M contiguous spot beams; and loading the new tracking beam BWV to a buffer.
