摘　　要：针对非均匀阵列引起的高旁瓣问题,提出一种基于二阶锥规划的任意形状旁瓣设计算法。算法通过在旁瓣区域附加多个二次不等式约束,从而有效抑制干扰、保持期望方向天线增益的同时,获得了期望的、可以任意控制的旁瓣波束响应。通过将优化模型转化为凸二阶锥规划问题,利用内点法可以得到有效求解。仿真试验表明:该文算法在能够获得任意形状期望旁瓣波束设计的同时,有效提高了波束形成器的输出信干噪比。最后,计算机仿真结果证实了算法的有效性和可行性。A new robust algorithm based on second order cone program,which can get sidetobe of any shape,is proposed for the problem of high sidelobe caused by nonuniform array configuration.By adding multiple quadratic inequality constrains to sidelobe regions,the method,suppressing interference effi ciently and retaining antenna gain of expectant aspect,achieves expected and controllable sidelobe of any shape.The optimization model can be converted into convex second order cone programming issue, which can be solved using the existing interior method.Computer simulations demonstrate that the pro posed method can achieve the lower sidelobe of any shape and get higher SlNR.Simulation results verify that the proposed algorithm is effective.
