基于DPSO算法的半球共形阵方向图综合

摘要

针对共形阵列天线方向图综合所需迭代次数大,且算法的收敛对初始值敏感问题,本文采用DPSO算法对半球共形阵赋形方向图综合进行了研究,通过对半球共球阵模型的建立,推导了所建模型的方向图函数.仿真结果表明,DPSO算法能够较快地综合半球共形阵的赋形方向图,是一种高效且实用的综合算法.%DPSO (Dichotomy Particle Swarm Optimization) algorithm was used to synthesize hemispherical conformal antenna array beam pattern,aimed at the accustomed algorithms of conformal array antenna beam pattern synthesis have a great iterative time and the constringency depending on the value of initialization.Based on the model of hemispherical conformal array,the beam pattern mathematic function of the array is put up.The result of simulation shows DPSO algorithm can form desired beam pattern quickly,and proves the method is effective and practicability.
