Abstract
This communication considers the synthesis of interleaved antenna
arrays with shared and inactive elements. A hybrid genetic algorithm
(GA) where the initial population is seeded with good solutions is proposed.
A number of seeding schemes are considered and themost effective of these
are identified. The proposed algorithm is shown to reliably produce results
with sidelobe level (SLL) values which are close to the optimum and to converge
faster than the other algorithms considered. However, some of the
seeding schemes mislead the GA and actually produce worse results than
random initialization.
