Abstract
An antenna system may include an antenna array configured to receive one or more signals. In embodiments, the antenna system further includes one or more signal processors configured to: determine a beamforming weight vector (W) for the antenna array; determine a first seeding weight vector (W) for the antenna array, wherein the first seeding weight vector (W) comprises a first nulling weight vector (W) or a second beamforming weight vector (W); determine a first nullforming adjustment factor (η) for the antenna array; calculate a first nullforming weight vector (W) based on at least the beamforming weight vector (W), the first seeding weight vector (W) and the first nullforming adjustment factor (η); and form a first antenna pattern based on the first nullforming weight vector (W) to generate a first antenna electronics (AE) output signal, wherein the first antenna pattern generates a first set of one or more nulls.
