AbstractNot Available Signal Systems Corporation proposes this research to improve current ASW system effectiveness by exploiting elastic wave re-radiation in multi-static sonars. We will use at-sea data, boundary element scattering models, existing echo detectors, advanced resonance extraction technologies and noise reduction techniques to conduct our research. The combination of these tools will demonstrate improvement in discriminating submarine echoes from other detections. In prior research, we have proven that our extraction technology can detect useful resonance phenomena in full-scale targets in mono-static geometries, but the reliable target to sensor ranges need to be increased. And, based on our work with acoustic scattering models, we believe that multi-static geometries will have stronger resonance amplitudes - thus motivating our proposed research. SSC also will pursue both coherent and incoherent sonar concepts, relying on noise and reverberation reduction techniques applicable to both types of sonars. In Phase I, we will process sonar echoes, comparing the resonance based classifier to existing data screening methods, as well as identify operational concepts compatible with resonant scattering theory and resonance extraction technology. These findings will be the foundation for a Phase II real time prototype system.
