Abstract
A method for reducing adaptive beam forming computation resources for estimating and updating a model of unwrapped beam weights. The optimal beam pattern weights of an antenna array are estimated using an adaptive beamforming algorithm. An initial model is created for either magnitude or phase components of the optimal beam pattern weights computed from the adaptive beamforming algorithm estimates. For each time step, a measurement of optimal beam pattern weights is estimated, using a reduced set of data comprising 5-20% of first samples of signal reference data. New beam pattern weights are computed using a magnitude Kalman filter (KF) and/or phase KF, wherein the computation resources required to obtain the new beam pattern weights are reduced by 80 to 90% over an adaptive beam forming algorithm.
