Single-Element Passive Time Reversal Mirror in Shallow Water Acoustics

Abstract

This project investigates a new approaches (Time reversal Mirror and Warping transform) for analysis of cross correlation functions of the noise field is shallow water, and for geoacoustic inversion. Data of experiment SW06 are used, results of inversion are reasonable and give good agreement with other data where comparison is possible. In experiment SW06 anomalously strong noise signals (noise burst) were registered, initiated by sediment saltation due to nonlinear internal waves (NIW trains).
