| 摘 要： | 本文提出一种任意平面阵列抑制干扰的方法.对任意平面阵列的接收信号进行多次正交变换,然后对变换后信号的自相关矩阵求平均值,所得矩阵应用最大信号与干扰加噪声功率比准则求得抑制干扰的权值.计算机模拟实验表明,该方法能有效抑制干扰且对干扰信号之间的相关特性没有要求.

| Abstract: | This paper proposes a method of interference suppression for a random planar array.Orthogonal transform are performed certain times on the signals.Then an average covariance matrix can result from all the covariance matrix of the transformed signals and from which a weight can be determined by a rule of Max SNR.The validity of the method is illuminated by computer simulation.And the method can constrain the interference efficiently and has no limits about the correlations among the interference signals. |
