In this paper, we present a novel improved wind‐driven optimization (IWDO) for transmit beamforming of phased array radar, which is assumed as a multiple constraints optimization problem. First, the emitted signal model and objective functions of optimization with constraints are presented. Second, all air parcels are divided into feasible and infeasible parcels, and then the target function and constraint violation of air parcels are evaluated. Finally, the constrained optimization problem is converted into the nonconstraint problem, and the proposed modified wind‐driven optimization (WDO) has been applied for the optimal design of beamforming with null steering. The simulation results show that the proposed method outperforms conventional optimization methods in the optimal beamforming by achieving more reduction in the null steering and obtaining accurate peak power.

基于约束风优化方法的相控阵发射波束成形

在本文中，我们提出了一种用于相控阵雷达发射波束成形的新型改进的风驱动优化（IWDO），它被认为是多重约束优化问题。首先，给出了发射信号模型和带约束的优化目标函数。其次，将所有航空包裹分为可行包裹和不可行包裹，然后评估航空包裹的目标功能和约束违规。最后，将约束优化问题转化为非约束问题，并将所提出的改进的风动优化（WDO）方法应用于具有零转向的波束成形的优化设计。
