Abstract

An adaptive beam forming system using a phased array antenna improves communication quality by beam forming adaptively to a communication environment having an interference signal. For adaptive beam forming, a good combination of the phases of the excited signals to each radiating element of the phased array antenna should be calculated. In this paper, improved particle swarm optimization algorithm that adds a re-spreading procedure according to particle density was proposed to increase the probability of good phase shift combination output.

위상 배열 안테나를 이용한 적응형 빔 형성 시스템은 간섭신호가 있는 통신환경에 적응형으로 빔을 형성하여 통신 품질을 향상시킨다. 적응형 빔 형성을 위해서는 위상 배열 안테나의 각 방사소자에 급전되는 신호의 위상을 우수한 조합을 산출해야 한다. 본 논문에서는 우수한 위상 천이 조합 산출 확률을 증가시키기 위해, 개치 밀도에 따른 재확산 절차가 추가된 개선된 개체 군집 최적화 알고리즘을 제안하였다.
