摘　　要：根据平面相控阵高灵活性低副瓣的需求,提出了一种基于非对称泰勒综合的平面阵列加权方法。相比于现存的主流方法,该方法适用于任意阵元排布的平面阵列,可对辐射方向图进行非对称的副瓣控制,还具有天线增益损失较小、幅度和相位同时加权、算法为非迭代算法等优点。给出了对称和非对称的泰勒加权公式,以及在不同阵面排布下的降副瓣效果。仿真结果表明该方法速度快,灵活度高,性能稳定。According to the requirements of high flexibility of low side lobes for planar phased array,this paper proposes a weighting method for planar array based on asymmetric Taylor synthesis.Compared with the existing mainstream methods,this method can apply to planar arrays with random array arrangement,can perform asymmetric side-lobe control to the radiation pattern,and has the advantages of small antenna gain loss,simultaneous weighting of amplitude&phase and algorithm being non-iterative.This paper provides both symmetric and asymmetric Taylor weighting formulas,as well as the side-lobe descending effect under different fronts arrangement.The simulation results show that the proposed method has fast speed,high flexibility and stable performance.
