摘要
Abstract
An effective subarray partition method based on genetic algorithm(GA)is proposed to divide a large array antenna into contiguous subarrays of unequal sizes.In the genetic algorithm,the main-to-side-lobe ratio(MSR)of pattern is taken as the fitness function.A subarray configuration with few obvious grat-ing lobes is obtained by adding constraint condition in the genetic evolvement.A two-stage subarray partition method based on genetic algorithm(GA)is proposed to divide a planar array antenna into contiguous subar-rays with ununiform structure.Using the two-stage subarray configuration,its pattern has high main-to-sidelobe ratio(MSR)in both the azimuth and elevation orientations.For the purpose of avoiding the influence of unequal noise power out of each subarray,an effectively adaptive beamforming algorithm based on singular value decomposition and eigenspace reconstruction is obtained.The simulation results are given to demon-strate the effectiveness and accuracy of this method.关键词
