水声信道的随机时变特性使得匹配滤波器的检测性能下降,参量估计误差增大。本文估计了这一影响,并给出了在这种情况下最佳时空处理器的结构和性能。讨论了实际实现的可能途径。本文修正了一些文章中关于部份相干信道的散射函数表达式的一些模糊概念。
The random time-varying characteristics of underwater acoustic channels make the detection performance of matched filter decrease and the error of parameter estimation increases. This article estimates this effect and gives the structure and performance of the best spatio-temporal processor in this scenario. Discusses the possible ways of actual implementation. In this paper, we modify some of the fuzzy concepts of some scattering function expressions for some coherent channels.
