CIRCULAR ARRAY ANTENNA OPTIMIZATION WITH SCANNED AND UNSCANNED BEAMS USING NOVEL PARTICLE SWARM OPTIMIZATION

Vvsss Chakravarthy, P. Mallikarjuna Rao

Abstract :

Sidelobe level suppression is a typical circular array (CA) optimization problem. Many conventional techniques are proposed in the due course of time which are computationally complexed and time consuming. As an alternative, several evolutionary and heuristics approaches have evolved for solving such problems. In this paper, a novel accelerated particle swarm optimization (APSO) is considered for solving circular array optimization problem. The APSO is implemented for CA synthesis with the objective of SLL suppression. The objective is achieved under scanned and unscanned beam conditions. A very low SLL of –25dB is observed when the main beam positioned at 00,150 and 300 . In all the cases the efficiency of the APSO is evaluated by the compå the generated radiation patterns with those obtained from uniform CA.
