摘要：
A method for steering nulls in the sum and difference patterns of a phased linear antenna array using only real weights is introduced. The proposed method decouples the weights so that a given jammer is associated with a given weight value. A change in the jammer's direction changes only its corresponding weight value without affecting the other nulls. The main beam is steered independently using a progressive phase shift. This allows the signal-to-jammer power ratio to be maximized with relative ease. The drawback of this method is that the number of jammers that can be nulled will be reduced to about a quarter of the number of array elements.
