Pattern synthesis of focal-plane array fed antenna with particle swarm optimization

摘要

A particle swarm optimization (PSO) algorithm is used to synthesis the pattern of the focal-plane array fed parabolic reflector antenna for deep-space exploration. Physical optics is used to compute the far field pattern of the antenna excited by the individual array elements of focal-plane array. Compared with the conventional conjugate field matching (CFM) method, this PSO synthesis algorithm can effectively control the pattern parameters such as side-lobe level, and the desired direction.
