| 摘 要： | 提出了一种存在阵列导引向量误差时的自适应波束形成算法。首先,文章提出了一个由接收信号协方差矩阵的噪声子空间和带有随机误差的期望信号导引向量构成的代价函数。然后基于非线性约束条件对此代价函数进行优化。新算法在期望信号导引向量存在误差的情况下仍能提供较好的输出SINR。仿真证明了新算法的有效性。

| Abstract: | A new adaptive beamforming algorithm is presented when the steering vector of SOI is imprecise.Firstly,the paper pro- rides a cost function comprising noise subspace of covariance matrix of receiving data and interesting signal steering vector with random errors.Then the cost function is optimized with nonlinear constraint condition.The new algorithm can provide well output SINR when the steering vector of SOI is imprecise.Simulations show the validity of the new algorithm. |
