最优广义线性最小方差无失真响应波束形成往往要求阵列导向矢量和信号非圆度必须为已知，为了突破此限制，基于最小方差无失真响应方法的约束条件提出两种波束形成方法：其一是先将阵列导向矢量和非圆度的不确定性转化为整体扩展导向矢量的不确定性，再规划波束形成；其二是利用信号结构信息来规划波束形成。仿真实验结果表明，新方法在突破此限制方面具有可行性。

Optimal widely linear minimum variance distortionless response beamforming normally requires available values of the array steering vector (ASV)and the signal non-circularity.To solve this strict limitation on the implementation of this beamforming,two approaches are proposed based on the limitation conditions of the minimum variance distortionless response beamforming.The first one translates the uncertainty constraints into the uncertainty for the whole extended steering vector. The second one uses the structure information of signal. Simulation results show that the two approaches can effectively implement beamforming without those limitations.
