Abstract

The following article describes and discusses the suitability of the particle swarm optimization (PSO) for the employment with blind adaptation of the directional characteristic of array antennas. By means of extensive simulations it was confirmed that the suggested PSO is able to follow dynamic changes in the environment. Based on these results a concept is discussed for a high-parallel optimizing procedure as distributed logic in application-specific integrated circuits (ASICs) or field programmable gate arrays (FPGAs). Thus an online procedure is available for time-critical applications of the adaptive beam forming
