摘要: 提出了一种基于0-1规划的稀布同心圆阵设计方法.将差分进化算法应用于0-1规划中,截取通过同心圆阵面主波束的多个切面,以切面内远场辐射方向图的副瓣电平、波束宽度和阵列单元数量为目标,降低相控阵成本.文中对一个9环和一个10环同心圆阵进行了仿真计算分析,证实了方法的有效性.使用该方法计算后,9环同心圆阵单元数量由原来的279个减少为161个,副瓣电平由原来的-17.4 dB降低为-20.8 dB,半功率波束宽度增大了0.22°.10环同心圆阵单元数量由原来的341个减少为190个,副瓣电平由原来的-17.4 dB降低为-23.9 dB,半功率波束宽度增大了0.79°.

Abstract: A sparse concentric ring array method based on 0-1 programming is proposed. Differential evolution algorithm is applied in the 0-1 programming. By obtaining multiple planes in the main lobe of the concentric ring array and assuming the side-lobe level, the beam width of the selected plane pattern and the element number of the array as the goal for optimization to reduce the cost of the concentric ring phased array. In order to validate the proposed method, a 9-ring and a 10-ring concentric circular array are calculated. The calculated results show that the element number of the 9-ring concentric ring array is reduced from 279 to 161, the side-lobe level is reduced from-17.4 dB to-20.8 dB, and the half power beam width increases by 0.22°. The element number of the 10-ring concentric ring array is reduced from 341 to 190, the side-lobe level is reduced from-17.4 dB to-23.9 dB, and the half power beam width increases by 0.79°.

Key words: 0-1 programming, sparse concentric ring array, differential evolution (DE) algorithm, low-cost phase array
