摘    要:从理论上分析了多子阵平板天线的方向图特性,指出其旁瓣电平难以通过传统的不等幅馈电技术得以抑制.以降低天线扫描范围内的最高旁瓣电平为目标,采用遗传算法对子阵间距进行优化,并在间距优化的基础上讨论了天线单元方向性与不等幅馈电技术对旁瓣电平的影响.仿真结果证明了理论分析的正确性,表明子阵间距优化可以显著降低天线的旁瓣电平,且...

Abstract:This paper analyzes the characteristics of the planar antenna with multiple subarrays,which indicates that the sidelobe of the antenna is difficult to reduce by the perturbation of amplitude weighting.In order to reduce the maximum sidelobe level of the antenna in the whole elevation scan range,the subarray distances are optimized by genetic algorithm(GA),and then the effects of antenna element directivity and amplitude perturbation on sidelobe suppression are discussed.Simulation results prove the validity...
Keywords:the planar antenna with multiple subarrays  satcom on-the-move(SOTM)  genetic algorithm  sidelobe suppression
