摘要
针对机会阵雷达发射波束的多目标优化问题,提出了一种基于二进制多目标风驱动优化算法的波束形成方法.以均匀多同心圆环阵列特性为基础,建立了发射信号的模型和目标优化函数.基于改进的多目标风驱动优化算法,实现了机会阵雷达圆阵的波束形成,即同时优化3 d B主瓣波束宽度和旁瓣电平.仿真表明：与基于传统粒子群算法（PSO）的波束形成性能相比,在使用更少圆阵阵元的情况下,本算法具有较低旁瓣和更窄的主瓣.
In order to realize the beamforming of opportunistic array radar,a beamforming method based on binary multi-objective wind driven optimization algorithm was proposed.Firstly,the emitted signal model and objective functions of optimization were presented for uniform multiple concentric circular arrays.Then,based on an improved multi-objective wind driven optimization algorithm,the beamforming of concentric circular arrays was realized with a trade-off between the 3 d B main beam width and sidelobe level.The simulations compared the proposed algorithm with the traditional particle swarm optimization（PSO） algorithm,and results show that the algorithm has a lower sidelobe and a narrower main lobe,in the case of using fewer circular array units.
