| 摘 要： | 一、引言利用波束形成器来确定单个声波的方位是比较成功的.当输入信号{x_k}可以看作是相互独立的平稳随机序列时,自适应波束形成器算法的收敛性得到较好的解决.6]首次讨论了具有非平稳相关输入的自适应波束形成器,给出了一个带限制的随机递推算法,并讨论了它的强一致性.但是,“限制”值的选取却完全取决于经验.如果选得不合适,有可能把最优解排除于我们所选定的范围之外.

| Abstract: | A new iterative algorithm for adaptive array processing with correlated and non-stationary noise is proposed which does not need to keep the estimates W_k in a boundedarea.Under some simple conditions we have proved the convergence of the algorithmin the sense of almost everywhere. |
