提出把混合优化算法IGA-EDSPSO(Improved Genetic Algorithm-Extremum Disturbed Simple Particle Swarm Optimization)和基于RWG基函数的MoM-PO混合算法用于最小阵元间距约束的稀布阵列设计中。通过调整阵元间距来优化辐射阵因子,改善了阵列天线的辐射性能。与以前的方法相比,该方法在处理大型阵列时,降低了对计算机资源的需求,有效地实现了考虑互耦情况下副瓣电平的抑制,真实地考虑了天线的整个结构对于方向图的影响,对低副瓣电平阵列天线的设计有一定的指导意义和参考价值。
In this paper, we propose a mixed-optimization algorithm IGA-EDSPSO (Modified Genetic Algorithm-Extremum Disturbed Simple Particle Swarm Optimization) and MoM-PO hybrid algorithm based on RWG basis function. The radiation array factor is optimized by adjusting the array element spacing, which improves the radiation performance of the array antenna. Compared with the previous method, this method reduces the requirement on the computer resources when dealing with large arrays and effectively suppresses the sidelobe level under consideration of the mutual coupling. It realistically considers the entire structure of the antenna for the pattern The influence of low sidelobe level array antenna design has some guiding significance and reference value.
