WEIGHTING TECHNIQUE FOR DETECTION AND LOCATION OF TARGETS BY TIME REVERSAL-REVERSE TIME MIGRATION MIXED METHOD

摘要：

　　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.
