给出了计算机模拟广义指向性信号的一种方法。其基本思想是:两个互不相关的高斯过程,它们的S-H矩阵乘积的协方差矩阵等于这两个过程协方差矩阵的s-H乘积。用对应于信号到达方向的时延或相移产生其中的一个过程,用RC低通信号经过适当的时延来造成另一个过程,这两个过程的S-H矩阵乘积就是所谓的广义指向性信号。本文还分析了这种广义指向性信号的波阵面空间相干损失与RC低通信号的时延之间的关系。 A method of computer simulation of generalized directional signal is given. The basic idea is: two unrelated Gaussian processes whose covariance matrix of S-H matrix products equals the s-H product of the two process covariance matrices. One of these processes is generated by a delay or phase shift corresponding to the arrival direction of the signal, and another process is caused by an appropriate delay of the RC low-pass signal. The S-H matrix product of these two processes is a so-called generalized directivity signal. The paper also analyzes the relationship between the wavefront space coherence loss of this generalized directional signal and the delay of the RC low-pass signal.
