摘要翻译：
第一部分介绍了一种智能声发射定位器，第二部分讨论了盲源分离、时延估计和两个连续声发射源的定位。声发射(AE)分析用于表征和定位材料中发展中的缺陷。声发射源常常产生各种统计独立信号的混合。声发射分析的一个难题是在各种信号源和混合方式未知的情况下，信号成分的分离和表征。近年来，基于独立分量分析(ICA)的盲源分离(BSS)被用来解决这些问题。本文的目的是证明ICA法在铝带试件上定位两个独立的同时有源声发射源的适用性。该方法对利用声发射分析进行飞机框架结构无损检测具有较好的应用前景。

英文摘要：
  Part I describes an intelligent acoustic emission locator, while Part II discusses blind source separation, time delay estimation and location of two continuous acoustic emission sources.   Acoustic emission (AE) analysis is used for characterization and location of developing defects in materials. AE sources often generate a mixture of various statistically independent signals. A difficult problem of AE analysis is separation and characterization of signal components when the signals from various sources and the mode of mixing are unknown. Recently, blind source separation (BSS) by independent component analysis (ICA) has been used to solve these problems. The purpose of this paper is to demonstrate the applicability of ICA to locate two independent simultaneously active acoustic emission sources on an aluminum band specimen. The method is promising for non-destructive testing of aircraft frame structures by acoustic emission analysis.
