Multi-Static Detection and Localization of Buried Targets using Synthetic Aperture Iterative Time-Reversal Processing

Abstract

The objective of this project is to develop bi-static applications of the iterative time reversal techniques to focus along the ocean bottom. Iterative time-reversal provides a simple solution for self-adaptive focusing on strong reflectors (i.e. scattering targets) located on the ocean bottom without relying on predictive or modeling capabilities of the environment and of the target of interest. These robust focusing properties are crucial for mapping large and uncharted areas with little signal processing effort involved. With the experiments planned by Schmidt et al, there will be enough data to understand the ultimate limitations of the proposed self adaptive methods.
