| 摘要: |
| 提出了一种新的存在相干信号时的最优波束形成算法。该方法首先利用二阶统计量信息估计合成方向矩阵，然后给出了一种根据期望信号的波迭方向寻找与之对应的合成方向矢量的方法．再据此估计最优权矢量。该方法与现有的同类算法相比计算量更小、鲁棒性更强。计算机仿真证明了算法的性能。 |

| A Robust Optimum Beamforming Algorithm for Coherent Signals |
|
| () |
| Abstract: |
| This paper proposes a new optimum beamforming algorithm in the presence of coherent signals. The idea and the procedure of the scheme are as follows. First, the second - order statistics of the received data are used to estimate the effective direction matrix. Then an approach is given, by which the synthetic direction vector corresponding to the expected signal is evaluated. Finally, the optimum weights are derived in the sense of maximization of SNR. Simulation results show the proposed method is computationally efficient and robust. |
