【摘要】 在复杂的电磁对抗环境中,需要增加波束的抗干扰能力。本文从低副瓣波束的凸规划形式出发,引入零陷约束,构建了一种低副瓣窄零陷的凸优化算法以消除副瓣区域内的强烈干扰。为了让干扰一直在零陷的角度区域内,引入导数约束来加深加宽其零陷,从而设计了一种低副瓣宽零陷的天线波束形成算法。最后通过数值实验验证,其结果证明了所提算法的有效性和可靠性。更多还原

【Abstract】 In a complex electromagnetic environment, it is necessary to increase the anti-interference ability of the beamforming. Starting from the convex programming form of the low sidelobe beam, the null constraint is introduced,this paper proposes a low sidelobe level and narrow nulling algorithm to eliminate the strong interference in the sidelobe region. The derivative constraint is introduced to deepen and widen the null to ensure the interference is in the nulling region. For this purpose, a low sidelobe and wide nulling array beamforming algorithm is designed. Finally, the effectiveness and reliability of the proposed algorithm are verified via numerical simulations.更多还原
