Abstract:
A method for producing an antenna weight vector for an N-element array antenna to for a designated antenna pattern having a single beam direction &thgr; beam and M null directions &thgr; null(1)-&thgr; null(M) (1=a) producing a work antenna weight vector for a (Nâˆ’M)-element array antenna to form a beam in the single beam direction; b) sequentially selecting one of the M null directions; c) producing a 2-element antenna weight vector for a 2-element array antenna to form a null in the selected null direction; d) multiplying the work antenna weight vector by a first weight and a second weight of the 2-element antenna weight vector to produce a first work weight vector and a second work antenna weight vector; e) appending 0 to a trail end of the first work weight vector and to a head of the second work weight vector to produce a first expanded weight vector and a second expanded weight vector, and adding the first expanded weight vector and the second expanded weight vector to produce a work antenna weight vector; and f) repeating the steps (c)-(e) until the M null directions have been selected, to produce a final work antenna weight vector as the antenna weight vector for an N-element array antenna.
