Robust Detection Algorithms for Time Reversal Matched Field Processing

To explain super resolution focusing achieved in time reversal, matched field processing (TR/MFP), an analytical multipath model based on geometric optics approximation with strong total internal reflections was presented in A. Asif and Q. Bai, (2006). This paper uses the multipath model to derive the system response matrix in TRTMFP and exploits the structure of the response matrix to develop detection algorithms for determining the number and locations of passive targets embedded in a random medium. Experimental results prove the accuracy of the algorithms in detecting passive targets
