A novel phase-only method for shaped beam synthesis and adaptive nulling

摘要

A new method for phase-only synthesis of linear array antennas is proposed. The phase distribution of the array excitation can be described by a weighted sum of proper basis functions. By optimising the weights of this sum, rather than the phase of each element, the problem becomes almost independent of the size of the array. The present work shows that with this method both beam shaping and interference nulling can be achieved. The very fast convergence of the optimisation makes it suitable even for real-time applications.
