【Abstract】 To make the maximum SLL of broadside array with equal excitation amplitude as low as possible, it is trade off studied that several GA schemes with different selection operators and crossover operators, and the optimized results of all the twenty four GA schemes are given. The results show that the key point of genetic algorithm design lies in proper population multiplicity. For example, the GA scheme with the truncation roulette selection and the uniform crossover can optimize the 48 element broadside array to maximum SLL of -26.3 dB.更多还原
