Abstract
Genetic Algorithm(GA) was used to synthesize the patterns of the focal plane array feeding parabolic reflector antenna in deep-space exploration.Physical optics was used to compute the far field pattern of the antenna for excitation of each of the individual array elements in focal-plane array.Various scanning patterns were synthesized for deep-space exploration with this GA.The results show the proposed algorithm can control the sidelobe level,more precisely synthesize the expected pattern,and expand the visual range of deep space exploration antenna.
