色噪声环境下自适应波束形成技术能有效适应阵列天线系统的实际应用场景。首先分析了色噪声环境下自适应波束形成技术性能,重点研究了有限次快拍下自适应波束畸变产生的原因,其次,在已知噪声协方差情况下,通过对噪声相关矩阵的改进设计,降低了色噪声协方差矩阵对自适应波束形成影响。计算机模拟仿真结果表明:提出的自适应波束形成算法在色噪声环境下具有较好的波束保形能力。
Adaptive beamforming technology in color noise environment can effectively adapt to the practical application of array antenna system. Firstly, the performance of adaptive beamforming in color noise environment is analyzed. The reason of adaptive beamforming in finite sub-snapshot is emphatically studied. Secondly, under the condition of known noise covariance, through the improved design of noise correlation matrix, The effect of color noise covariance matrix on adaptive beamforming is reduced. Computer simulation results show that the proposed adaptive beamforming algorithm has better beamforming capability under color noise environment.
