Abstract:

The long-term goal of this research is to understand both acoustic and microwave scattering from rough water surfaces sufficiently well to be able to implement operational models for wind speed prediction and, if possible, to remotely sense microscale breaking on the sea surface. Previous work that we carried out as part of the WAVES BAA program had shown the importance of bound, tilted Bragg scatterers in both microwave and acoustic scattering from rough water surfaces. Our core scientific objective in this work was to elucidate the phenomenon of scattering from bound, tilted waves by making controlled wavetank measurements, and interpreting our results by way of improved theories.
