Title: Structural Monitoring of a Weapons Test Unit Using Imaging Methods for Dynamic Signature Analysis

Abstract

A methodology to identify structural changes in weapons systems during environmental tests is being developed at Lawrence Livermore National Laboratory. The method is coherence based and relies on comparing the ''dynamic signature'' response of the test article before and after an environmental test or test series. Physical changes in the test article result in changes in the dynamic signature and are mapped to an image matrix where a color scale represents changes in sensor-to-sensor coherence. This methodology is convenient because it allows an image to represent large amounts of information in a very compact form, where even subtle system changes may be easily and quickly identified. Furthermore, comparison of the dynamic signature response data before and after any test event can be made on a quasi-real-time basis. This approach is particularly useful on large and/or complex test articles where many sensors are present, and large volumes of data are generated.
