摘要
天线方向图综合作为阵列天线设计与实现的一项重要技术,对复杂系统的随机全局最优化问题提出了更高的要求。本文基于基础差分进化算法,对实际工作中经常遇到的阵列方向图宽波束设计问题和低副瓣设计问题,进行差分进化算法的优化设计与实现。算例的优化过程和结果表明,差分进化算法与传统优化算法相比,具有不需要初值信息,优化速度快,善于处理多参数优化问题等优点,有一定实用价值。
Antenna pattern synthesis,as an important technology in the design and implementation of array antennas,puts forward higher requirements for the stochastic global optimization of complex systems.In this paper,based on the basic differential evolution algorithm,the optimal design and implementation of the differential evolution algorithm are carried out for the design of the wide beam of the array pattern and the design of the low side lobe of the array pattern that are often encountered in practical work.Compared with the traditional algorithm,the differential evolution algorithm does not need initial value information,the optimization speed is fast,and it is good at dealing with multi-parameter optimization problems.
