摘要：

为了克服基本入侵杂草算法在处理高维数复杂问题时收敛速度慢、易陷入局部最优的问题，将简化的二次插值法作为局部搜索方法嵌入到入侵杂草算法中，提出了一种混合入侵杂草算法．该算法利用简化的二次插值法较强的局部搜索能力来增强算法的整体收敛性能，提高收敛速度和计算精度．仿真结果表明，该算法在阵列天线波束赋形问题中，整体性能优于基本入侵杂草算法及其他同类算法．

关键词: 阵列天线, 波束赋形, 入侵杂草算法, 简化的二次插值法

Abstract:

For overcoming the problem of slow convergence speed and local optimum in handling the high-dimension complex problem by the Invasive Weed Optimization Algorithm(IWO), a hybrid Invasive Weed Optimization Algorithm(HIWO) is proposed by integrating the Simplified Quadratic Interpolation(SQI) method into the IWO. The SQI Method is integrated in the IWO as a local search operator to enhance the performance of the algorithm, improve the convergence speed and computation accuracy. Simulation results for different design requirements show that the proposed algorithm performs better than other existing algorithms in the problem of shaped beam synthesis of array antennas.

Key words: array antennas, shaped beam antennas, invasive weed optimization, simplified quadratic interpolation
