Electromagnetic Time Reversal Imaging: Analysis and Experimentation

Abstract

In this project, we investigated time reversal (TR) based signal processing theory and algorithm development for target detection, localization, imaging, and interference cancellation in the electromagnetic domain. We conducted a thorough study of time reversal for these applications, developed new suites of detection and imaging algorithms and derived analytical expressions quantifying their performance, confirmed the analytical results with extensive numerical simulations, and demonstrated the gains in performance over conventional methods using real world electromagnetic data. The algorithms developed included TR-channel matched detectors, TR adaptive interference canceller (TRAIC) and TR beamforming for imaging and localization, and TR-SAR for improved ghost removal in SAR imaging. Our algorithms, analytical, and experimental findings have been consistently summarized in the annual reports we have submitted and in over 30 publications submitted to the technical literature (Journals and Conferences.) This Final Report summarizes the major achievements of the program.
