Abstract

Weighting technique is applied to detection and location of targets using the time reversal-reverse time migration mixed method and obtain the better focusing effect. In this paper, two different weighting techniques are weighting of distance between emission and reverence element and time-gate weighting, used to obtain better focusing effect. Therefore, weighted technology can effectively make the main peak more prominent, better location of the target.
