摘要
提出一种应用于均匀直线阵列的干扰抑制方法.对均匀直线阵列进行虚拟平移对信号作变换,应用最大信号与干扰加噪声功率比准则得到权值.该方法克服了使用空间平滑技术带来的阵列孔径减小的负面效果.计算机模拟实验表明该方法性能优越.
This paper addresses a novel method of the interference suppression for a uniformly-spaced linear array. Through some virtual translation on the array, received signals may be virtually transformed. And the signals are transformed correspondingly. Then a weight is obtained by a rule of Max SNR. This method overcomes the disadvantage of caliber reduction by the spatial averaging technique. The validity of the method is illuminated by computer simulation.
