Far Field Pattern: Shaped Beam
A deterministic approach has been developed at LEMMA for the mask-constrained power pattern synthesis of shaped beams through one-dimensional sparse arrays having uniform-amplitude excitations (and variable phases) . The approach includes the well-known density taper procedure as a special case. The corresponding technique, which exploits an analytical formulation of the problem and convex programming routines, results in fast computation and is able to achieve optimal solutions without recurring to any global optimization. On the basis of such results, LEMMA also proposed a simple approach to the design of circular-ring isophoric sparse arrays .
