Hybrid optimisation algorithm and its application for pattern synthesis of planar arrays

Hybrid optimisation algorithm and its application for pattern synthesis of planar arrays

A hybrid approach to the synthesis of sparse arrays radiating shaped or focused beampattern is presented in this paper. Specifically, an iterative scheme is used where the prescribed pattern response in the mainlobe peak direction is cast as a multi-convex problem at each step that the non-convex lo...
