The synthesis of difference patterns via linear arrays, the elements of which are fed with the same amplitude, is proposed as a way to simplify the receiving chain and improve efficiency of the antenna. The problem is solved by means of suitable analytical procedures based on a ‘density taper’ approach. In particular, two different techniques are introduced and compared on the basis of a set of numerical examples. It is shown that one of them definitely outperforms the other one, and that constraints of practical interest can be satisfactorily fulfilled.
