摘　　要：提出一种随机阵型阵列多指标优化方法。通过对阵元域权值、副瓣级等综合约束,将阵列波束优化问题等效为凸优化问题,并得到数值解。阵列波束形成及凸优化理论分析及仿真实验表明,所提方法对于任意阵型阵列,可在保证指定方向阵列接收功率最大的前提下,抑制特定方向强干扰,设定阵列副瓣级,并获得当前条件下最小的波束宽度,对相关工程应用问题起到参考作用。An arbitrary geometry array beampattern optimization method is proposed.Through weighting comprehensive constraints of array unit field and array sidelobe level,a beampattern optimization numerical solution with convex optimization is gotten.According to theory analysis and simulation experiment result,the array output power at a certain direction can be maximized with an arbitrary array geometry.The sidelobe level can be set,the interfering signals can be suppressed and a narrowest beam width can be gotten.The method is useful in reality applications.
