一种基于差分进化算法的长波天线地网优化研究
An Optimization of Long-Wave Antenna Ground Network Based on Differential Evolution Algorithm

长波发射天线工作频率低，对应波长越长，常规工程中建设的天线均属于电小天线，其辐射电阻较小，需严格控制地损耗电阻，保证天线辐射效率。地损耗电阻主要取决于地网形态的设计，本文提出一种改进的差分进化算法，针对长波天线的地网设计方案各方面状态进行优化设计，并通过一个计算实例进行计算验证，所采用的优化算法可以实现一定限定范围内的最优化设计。
The long-wave transmitting antenna has a low working frequency and a long corresponding wavelength. The antennas constructed in conventional engineering are all electric small antennas, and their radiation resistance is small, so the loss resistance should be strictly controlled to ensure the radiation efficiency of the antenna. The ground loss resistance mainly depends on the design of the ground network. In this paper, an improved differential evolution algorithm is proposed to optimize all aspects of the state of the ground network design scheme of the long wave antenna, and a calculation example is used to verify that the optimization algorithm used can achieve the optimal design within a certain limited range.
