THE PRINCIPLE OF DETECTION AND LOCATION OF THE TARGET IN MULTI-LAYERED MEDIA BY TR-RTM MIXED METHOD
A time reversal (TR)-reversed time migration (RTM) mixed method has recently been proposed for locating targets in two-layered media.The experimental results have showed that the TR-RTM method is an effective method for determining the target location in two-layered media.However, for targets in multi-layer media, it is more difficult to distinguish the target signal and the interface signal because of the existence of multiple interfaces.The detection and location of targets in multi-layered media are studied.Through numerical simulation analysis, this method has been proved to be effective method for determining the target location in multi-layered medium.
