In inverse problems, redatuming data consists in virtually moving the sensors from the original acquisition location to an arbitrary position. This is an essential tool for target oriented inversion. An exact redatuming method which has the peculiarity to be robust with respect to noise is proposed. Our iterative method is based on the Time Reversal Absorbing Conditions (TRAC) approach [1] and avoids the need for a regularization strategy. Numerical results and comparisons with other redatuming approaches illustrate the robustness of our method.

通过TRAC方法进行全波形重新基准：面向目标的逆问题的第一步

在反问题中，重新计算数据包括将传感器从原始采集位置虚拟移动到任意位置。这是面向目标的反演的基本工具。提出了一种精确的重新标定方法，该方法具有针对噪声的鲁棒性。我们的迭代方法基于时间逆转吸收条件（TRAC）方法[1]，并且避免了使用正则化策略的需求。数值结果和与其他重新引用方法的比较说明了我们方法的鲁棒性。
