摘要: |
针对最坏情况下性能优化的稳健自适应波束形成,提出一种自适应方向图的副瓣控制方法。该方法通过在副瓣任意区域设置多个二次不等式约束,对副瓣增益进行控制,从而可将方向图副瓣电平严格控制在期望值以下。该方法的优化模型可转化为凸二阶锥规划问题,利用内点法可有效求解实现。计算机仿真结果表明存在波束指向误差情况下,该方法既能获得指定的较低副瓣电平,又不带来干扰抑制性能的损失。 |

Abstract: |
A sidelobe control method is proposed for robust adaptive beampattern based on worst-case performance optimization. Multiple quadratic inequality constrains are added to arbitrary sidelobe regions, which can achieve lower sidelobe level as well as adaptively suppress interference. The optimization model can be converted into convex second-order cone(SOC) programming issue, which can be solved efficiently using the existing interior point method. Simulation results demonstrate that in the case of beam pointing error, the approach proposed can obtain the prescribed low sidelobe without performance loss. |
Keywords: robust adaptive beamforming adaptive beampattern sidelobe control second-order cone programming |
