摘要 提出了一种鲁棒波束形成算法。给出了一种基于可变角加载形式的方向图权向量形式,然后利用非线性约束条件对此权向量进行优化。新的算法可以在期望信号导引向量存在误差的情况下提供较好的输出SINR。仿真证明了新算法的有效性。 A new adaptive beamforming algorithm is presented. Firstly, paper provides a weight vector of pattern based on alterable diagonal loading. Then the weight vector based on alterably diagonal loading is optimized with nonlinear constraint condition. The new weight vector can provide well output SINR when the steering vector of SOI is imprecise. Simulations show the validity of the new algorithm.
