摘要
现有天线方向图综合方法难以在多零陷生成的同时对旁瓣进一步抑制，提出一种基于动态权的目标函数模型．经过对目标函数适应度的测试，证明该函数模型具有良好的收敛特性．实验证实，在10元阵列的归一化方向图综合中，该模型可使旁瓣降低3～4dB．
As the current pattern synthesis of antenna arrays can not be used to suppress the sidelobe as well as keep with several prescribed nulls, a dynamic weight objective function model was proposed. According to the test of the fitness of objective function, the results demonstrate that this function model has a nice convergence characteristic. The experimental results show that about 3 to 4 dB reduction of side lobe can be obtained in the normalized patterns of the 10-element linear array by using the novel function model.
