摘　　要：基于优化天线阵列波形的目的,本文采用QPSO算法,对建立的九天线圆阵列模型进行波束赋形优化。本文通过九天线圆阵列模型进行MATLAB仿真实验,结果表明,经过QPSO算法进行优化后,主瓣方向还是保持一致,主瓣增益增大了6 dB;而采用QPSO算法对本文提出的九天线圆阵列与八天线圆阵列进行波形优化的仿真实验表明,主瓣方向还是保持一致,主瓣增益增大了19 dB,并且降低旁瓣个数,验证了模型的可行性。For the purpose of optimizating of antenna array waveform,we used QPSO algorithm to perform beamforming optimization on the nine line circle array model established in this paper.Through the MATLAB simulation experiments with nine circular antenna array model ,the results showed that,after QPSO algorithm optimized, main lobe direction was consistent, main lobe gain increases by 6 dB：while compared with the eight circular antenna array , we used the nine circular antenna array QPSO algorithm proposed in this paper for simulation waveform optimization simulation , the results showed that the main lobe direction was consistent, main lobe gain increased by 19dB, and reduced the number of side lobes, which verified the feasibility of the model.
