A null direction control method allows optimum antenna weights forming designated null beam directions without calculating an inverse matrix. In an N-element array antenna, a designated null beam antenna pattern is obtained by processing a 2-element antenna weight vector forming a null in a sequentially selected one of M designated null directions and a (N-M)-element antenna weight vector forming a beam in a designated beam direction to produce an antenna weight vector for the N-element array antenna. The final antenna weight vector is calculated by incrementing the number of elements of a work antenna weight vector each time a null is formed in a sequentially selected one of the M designated null directions.</PTEXT>
