Abstract: We have developed a method for Time Reversal Barrier (TRB) target detection using existing Coherent Active Source and Digital Vertical-Line-Array Receive Sonobuoys. Existing multistatic sonobuoy ASW systems are unable to exploit the forward scattering strength of submarine targets due to the blinding presence of the direct blast. TRBs take advantage of target forward scattering providing a significant improvement in detection capability. This is important given the emergence of stealthier adversaries with lowertarget strengths. At-sea tests are anticipated in Q2-Q3, 2010. Our company specializes in acoustics, vibrations, hydrodynamics and signal processing for DoD and commercialapplications and seeks relationships with ASW contractors and Navy program managers to transition this technology to the Airborne-ASW community. This technology may also be applied to other multistatic sonar systems.
