摘　　要：本文提出一种遗传算法和凸优化相结合的方向图模值综合方法.将方向图主瓣的相位作为遗传算法的优化变量,结合期望主瓣的模值构造适应度函数.利用凸优化求解该适应度函数可得相应个体适应度的最优值,提高了算法的搜索性能.相位的优化使得本文方法综合结果与阵列的参考点无关,而且适用于任意阵.仿真数据结果验证了方法的有效性.A pattern synthesis with desired magnitude response based on the combination of genetic algorithm and convex optimization is proposed.The phase in mainlobe is used as the optimization variables for genetic algorithm,and the fitness function is constructed with the desired magnitude of mainlobe.The optimal fitness degree for the corresponding individual can be obtained through solving the fitness function with the convex optimization,which greatly improves the algorithm search performance.The phase optimization makes the synthesis result with the proposed algorithm has no relation to the array reference point and the algorithm is suit for the arbitrary array synthesized.The validity of method is confirmed by the result of the simulate data.
