声学，电磁和弹性波场的理论，在控制方程，平面波，球面波（绿色函数）和散射场表示的共同方面进行了讨论，导致建模和成像算法的统一推导。后者需要线性化的逆散射问题。混凝土中的钢筋束管道的位置和评估的应用，利用合成以及实验数据最终在现实生活中的例子，从一座桥的数据。(C)2006爱思唯尔有限公司保留所有权利。
The theory of acoustic, electromagnetic and elastic wave fields in terms of governing equations, plane waves, spherical waves (Green functions) and scattered field representations is discussed under common aspects leading to a unified derivation of modeling and imaging algorithms. The latter require a linearization of the inverse scattering problem. Applications referring to the location and assessment of tendon ducts in concrete are presented utilizing synthetic as well as experimental data culminating in a real-life example for data taken from a bridge.
