Abstract
Supported by ONR for the past decades, researchers have succeeded in 'imaging' underwater with background noise, 'Acoustic Daylight.' In this paper, the authors will discuss their success in detecting underwater objects in background noise. This detection method is not an imaging technique. It is a broadband resonant scattering detection technique based on the theory of resonance and/or resonant scattering of the elastic sphere illuminated by 'Acoustic Daylight.' Using the resonant detection technique, it appears that underwater targets can be detected and identified in background noise, 'Acoustic Daylight.'
