Abstract

Time reversal (TR) refocuses the incident acoustic field back to the origin of a probe signal regardless of the complexity of the medium. However, the operation of a TR requires a cooperative probe source. This is impossible in passive work mode. In this paper, a dummy time-reversal mirror (DTRM) method is discussed to introduce the concept of time-reversal into underwater passive location. Several ocean acoustics experiments demonstrating the implementation of DTRM have been conducted. The proposed method is useful while at long source-receive ranges, or while object is moving.
