Second-order Cone Programming Beamforming Optimization Method with Dynamic Constraints on Weight Coefficient Amplitudes

摘要:

针对收发（transceiver，TR）组件可调衰减范围约束导致阵元级模拟加权波束优化性能受限的问题，提出了一种权系数幅度动态约束下的二阶锥规划波束优化方法。该方法在窄带波束优化统一形式基础上，增加权系数幅度动态约束，对阵列天线阵元权系数进行优化求解。经仿真验证：在主瓣响应误差最小、稳健性最优等多种优化条件下，该方法均能得到适应TR组件可调衰减范围的波束优化权系数，具有较好的工程应用价值。

Abstract:

To address the performance limitation of element-level analog weighting-based beamforming imposed by the adjustable attenuation range constraints of transceiver(TR) components, a second-order cone programming (SOCP) beamforming optimization method with dynamic constraints on weight coefficient amplitudes was proposed. Building upon a unified narrowband beamforming optimization framework,the proposed method incorporated dynamic constraints on weight coefficient amplitudes to optimize the antenna array element weights. Simulation results demonstrate that under various optimization criteria, including minimum mainlobe response error and optimal robustness, the proposed method effectively generates beamforming weight coefficients that comply with the adjustable attenuation ranges of TR components, demonstrating significant practical engineering value.
