摘要
提出一种基于改进遗传算法的稀布面阵综合的新方法。该方法通过对阿基米德螺线参数的合理设置,确保了阵元在沿阿基米德螺线的轨迹分布时依然能够满足阵元数约束、孔径约束和最小阵元间距约束,从而将稀布面阵的优化问题转化为非对称线性阵列的稀布问题,这就大大降低了问题的复杂程度。仿真实验结果证明了该方法的有效性。
A new method of sparse plane arrays synthesis based on improved genetic algorithm is presented. The constraints of array element number, aperture and minimum array element space can still be met by setting rational parameters of the Archimedes Spiral when array elements are distributed along track of the spiral. So optimization of sparse plane array is converted into sparse array of asymmetrical linear arrays, this will reduce the complexity of solving problems greatly. The simulation results show effectiveness of the method.
