摘要
针对舰载通信天线布置特性,综合应用典型启发式随机搜索技术(RHS)和数值仿真技术,对传统天线布局方法进行改进.以遗传算法为例,建立其与舰载天线优化布局的两类对应关系:天线优化布置参数与遗传算法特征值的关系;天线优化布置操作与遗传算子的关系.通过矩量法、多目标优化算法和权重系数变化法,对天线优化布局问题进行量化分析,解决了多参数协调控制复杂平台天线优化布局问题.在此基础上构造了一个具有理想导电面的舰船平台,以具体实例验证了理论模型的正确性.最终数值计算结果和试验结果符合较好,表明采用RHS技术获取的天线布局方案优于传统的天线布局方法,且可兼顾精度和效率.
According to the characteristics of ship-boarded antenna arrangement,the traditional approach to optimization of antenna arrangement was improved by using typical random heuristic search and numerical simulation technology.The optimization of antenna arrangement controlled by many parameters was quantitatively solved by using the moment method(MoM),multi-objective optimization algorithm and the weight coefficients approach.An ideal naval vessel was modeled.The correctness of proposed theoretical model was validated by the simulation results.The numeric result is consistent with experiments result. It is indicated that the approach of antenna placement based on RHS is superior to the traditional approach,and can take account of accuracy and efficiency.
