SYSTEM AND METHOD FOR NULLFORMING WITH ANTI-JAM ANTENNA ELECTRONICS

摘要

An antenna system may include an antenna array (104) configured to receive one or more signals. In embodiments, the antenna system further includes one or more signal processors (106) configured to: determine a beamforming weight vector (W_bf) for the antenna array; determine a first seeding weight vector (W_seed1) for the antenna array, wherein the first seeding weight vector (W_seed1) comprises a first nulling weight vector (W_nul1) or a second beamforming weight vector (W_bf); determine a first nullforming adjustment factor (η₁) for the antenna array; calculate a first nullforming weight vector (W_nf1) based on at least the beamforming weight vector (W_bf), the first seeding weight vector (W_seed1), and the first nullforming adjustment factor (η₁); and form a first antenna pattern based on the first nullforming weight vector (W_nf1) to generate a first antenna electronics (AE) output signal, wherein the first antenna pattern generates a first set of one or more nulls.
