Synthesis of Radiation Patterns of Arrays with Defined Sidelobe Structure Using Accelerated Particle Swarm Optimization.

Pattern synthesis from array antennas has become a commonly problem to address. Several standard and conventional techniques are available in the literature for the above purpose. Depending on the desired shape of the pattern, the methods are chosen for example, Taylor considered a continuous line sources and generated narrow beams with the desired sidelobe levels of equal height close to the main beam. Elliot has reported a method to generate unsymmetrical patterns. There are some applications where the restricted sidelobes in the mid of the sidelobe region are required. To generate such patterns, no work is available in the literature. In view, of this intensive investigations are carried out to generate such patterns. Accelerated Particle Swarm Optimization is applied to optimize the above patterns. The simulated patterns are presented for both small and large arrays. [ABSTRACT FROM AUTHOR]
