用时域包围法寻找粗糙背景中的障碍物

Masaru Ikehata

摘要:

介绍了一种利用时域波动现象进行穿墙成像的数学方法。该方法利用有限时间内的单个反射波,给出了在一般粗糙背景介质中是否存在可穿透障碍物的判据。此外,如果障碍物存在,障碍物和初始数据的支持中心点之间的距离的上下估计。作为证据的潜在的方法也给出了两个应用程序。

英文摘要:

A mathematical method for through-wall imaging via wave phenomena in the time domain is introduced. The method makes use of a single reflected wave over a finite time interval and gives us a criterion whether a penetrable obstacle exists or not in a general rough background medium. Moreover, if the obstacle exists, the lower and upper estimates of the distance between the obstacle and the center point of the support of the initial data are given. As an evidence of the potential of the method two applications are also given.
