摘要

针对时调共形阵列天线多波段方向图合成问题，提出了一种低旁瓣电平和差波束形成的二次凸优化算法。本文通过在中心频段产生空点和优化阵元的导通时间来合成具有低旁瓣电平的差分波束。通过优化阵元的导通时刻，实现了一阶边带的和波束形成和旁瓣抑制。该算法具有良好的旁瓣抑制性能和角扫描性能。圆形天线和卫星阵列天线的仿真结果验证了该算法的有效性。

Multiband Pattern Synthesis of Time-Modulated Conformal Array with Quadratic Convex Optimization Algorithm

Aiming at the multiband pattern synthesis problem of time-modulated conformal array antenna, a quadratic convex optimization algorithm is proposed for sum and difference beamforming with low sidelobe levels. This articles method synthesizes a difference beam with a low sidelobe level by generating nulls at the center frequency band and optimizing the switch-on duration time of array elements. And the sum beamforming and sidelobe suppression of the first-order sideband are realized by optimizing the switch-on instant time of the array elements. The proposed algorithm has excellent properties of sidelobe suppression and angular sweep. The simulation results of circular and satellite array antenna verify the effectiveness of the algorithm.
