摘　　要：波束赋形可以得到雷达系统所希望的理想辐射波束,然而传统分析方法存在理论分析繁琐、计算量较大的缺点,不利于在实际的工程应用中得到推广和使用。文章提出了一种基于粒子群算法对波束赋形的研究方法,具有代码简单、计算快速准确等优势。根据直线阵列的基本理论建立基本模型及方向图波瓣评估函数,最后得出两个案例的分析结果。计算结果验证了该方法的可行性和高效性,利于在实际工程中得到应用。The ideal radiation beam desired by the radar system can be obtained through beamforming.However,the traditional analysis method has the disadvantages of complicated theoretical analysis and large amount of calculation,which is not conducive to the promotion and application in practical engineering.This paper proposes a research method for beamforming based on particle swarm algorithm.This method has the advantages of simple code,fast and accurate calculations,etc.According to the basic theory of linear array,the particle swarm model and the pattern lobe evaluation function are established.Finally,the analysis results of two cases are obtained.The calculation results verify the feasibility and efficiency of the method,which is beneficial to be applied in actual engineering.
