摘要翻译:
计算时间反转成像可以用来定位已知背景介质中多个散射体的位置。在这里,我们讨论了一种计算时间反转成像的稀疏近似方法。该方法完全建立在频域内,除了成像外,它还可以用于去噪,并在中等噪声水平下确定散射系数的大小。

英文摘要:
Computational time reversal imaging can be used to locate the position of multiple scatterers in a known background medium. Here, we discuss a sparse approximation method for computational time-reversal imaging. The method is formulated entirely in the frequency domain, and besides imaging it can also be used for denoising, and to determine the magnitude of the scattering coefficients in the presence of moderate noise levels.
