摘要
研究了线性约束最小方差(Linearly Constrained Minimum Variance,LCMV)波束成形的基本原理,提出将其应用于实际无线电监测工作中,实现不同波达方向的同频信号分离,仿真实验结果表明,波束成形算法可以突出增强某一特定方向的信号增益,同时抑制其他方向的信号增益,达到同频信号分离的效果。
In this paper,the basic principle of linear Constrained Minimum Variance(LCMV)beamforming is studied,and it is proposed to be used in the actual radio monitoring work to realize the separation of the same frequency signals with different arrival directions.The simulation results show that Beamforming algorithm can enhance the signal gain in one particular direction and suppress the signal gain in other directions,so as to achieve the effect of signal separation in the same frequency.
